abunda_amazon_reviews This is my third ebike. The packaging of the bike during shipment was poor. I received the bike with some damage. In particular, the gear shift indicator was broken. After opening the box it looked as though the bike was packaged with whatever packaging material they had laying around. The bike definitely was not secure inside the box. I bought the bike particularly for it's compact size, folding capability and FULL suspension. The ride is fantastic. At 245 lbs, this bike can handle my size with no problem. It has good acceleration and a top speed of 28mph. There are only 3 pedal assist settings to choose from. Speed 1 is 18-20 mph, speed 2 is 23-25 mph and speed 3 is 28 mph. It would have been nice to have a setting for a lower speed in addition to a cruise control. The battery life has been moderate so far, I haven't done a full range test yet. Overall, I'm currently pleased with this Rattan Bike. Update 02/19/20 Odometer is currently 62 miles. So, the battery life is "meh" running throttle only. I'm currently looking into paralleling another battery to increase my Ah. There is a BIG correction on my part when it comes to the pedal assist. Before I stated there were only 3 options with limited speed. Come to find out, the speed controller is highly programmable. You can pick the number of pedal assist "gears" you'd like ie. 0-3, 1-3, 0-9, 1-9. In addition, you can indicate the percentage of battery output to each gear. Also, you can adjust the maximum speed of the bike.;;Reviewed in the United States on February 7, 2020;;4.0 out of 5 stars;;Love the bike;;Amazon Customer;;;I think the bike hardware is OK. The brakes feel great, but the rear squeals when applied either hard or soft. The rear wheel spokes crackle and pop as I ride or coast. The left pedal pops under my foot on the up stroke. The full suspension and fat tires are very nice. I have ridden on a sandy beach, a rocky beach, up and down mountain trails, and I have no complaints about the bike's ability to handle everything. But that's what a full suspension fat tire bike should do and can do. The software is horrible. I am a professional software developer. I run my own software consulting company, so I can spot lousy software a mile away. In no particular order: 1) The % battery indicator is comically bad. One time the bike shut off. I pedaled back to my RV and plugged it in and as soon as it booted it showed 46% on the meter. So, should I assume it shuts off somewhere around 40%? After that I took it on an arduous 26 mile round trip trek to a store. There was 1000 ft elevation change from start to the turn around point. I went through dry desert wash with plenty of soft sand, then on lousy roads that shook the hell out of my RV and also the bike, then on OK city streets to the store. There were plenty of ups and downs. The gauge showed 100% for the first 2/3rds to the store, which was mostly downhill, but also against a 20mph wind. I was pedaling downhill to overcome the wind. Then it fell like a rock to around 70%. I was in a panic in the store because I figured it would shut off going up hill on the return at around 40%. On the return up and down city streets, and up a very long stretch of road that was a pure up hill climb, it hovered around 70%. Anytime I pedaled it was using an indicated 330 watts, and I was always pedaling when not going down hill. I knew I was draining it. The last 4 miles were on a horrible wash board dirt road that was up hill. The indicator dropped to 45% at the start of that. I was expecting to lose the much needed boost at any moment.... I was constantly checking the gauge just waiting for the bike to die. But the indicator hovered around 45% until I got back. By my calculation, using the indicated 330watts, I estimate I used 450watt hours of juice which is damn close to the expected 500 watt hours of the battery. In other words, I drained that battery. A battery indicator that basically has 3 values (100%, 70% and 45%) but pretends to give you 100 values is hideously bad. It is obvious that they are only measuring the battery voltage, which is just plain dumb for a lithium battery. They should measure the watts over time and report that. 2) The thumb throttle only works when you are not pedaling and when the mode setting is set on a boost mode. This is silly. Just make the throttle supply juice to the motor whenever it is pressed. There is no excuse to make the user plop the pedal assist thingy into some arbitrary number to make the throttle work. Additionally they should adjust the gain on the throttle so that the boost is linear across the range. It feels like all the boost occurs in the second half of the throw. 3) When pedaling it only delivers a maximum of 330 watts of boost. If I stop pedaling, and go full throttle, it indicates over 500 watts. (I believe the watt indicator, if you go full throttle, then rotate the pedals without putting muscle into it, the boost obviously drops off matching the watt indicator.) What is this nonsense? When you go up a steep hill pedaling with all your might, you want all the boost you can get. I paid for a 500watt bike. I want the full 500watts when pedaling! 4) The regeneration is useless but it should be very useful. We don't buy an e-bike to generate electricity, we want to capture wasted energy when we need to slow down. The user interface should be just like a brake, because that is what regen is. It is a brake. It is not a strong brake, but I would use that regularly as I check my speed on steep down hills. That is not possible on this bike because you have to use the more cumbersome + and - mode buttons to get into mode 0 to generate. I rode on some fun roller coaster trail, but there is no chance of using regen on the down the hill sections, because it will take too long to flick back on the mode that will do boost for the uphill section. You have to get the mode thing back to non-zero in order for either pedaling or the thumb throttle to supply boost. Plus you cannot modulate the regen, so you cannot modulate this brake. (Note: I suspect that the motor does not have permanent magnets and thus it cannot generate unless the speed is above 16mph, and thus even with the best user interface it will not be very useful) 5) The modes are just plain stupid. You can select from a variety of mode sets in the "advanced" settings. A mode set is, for example, 4 different values of pedal assist. In the advanced settings you can tell it how much boost in mode 1, and 2, and 3, then repeat this for any number of additional mode sets. Why anyone would want multiple sets is beyond my comprehension. Furthermore, the boost is a number from 0 to 100 that has no meaning. I assume it is a percent, but a percent of what? I don't know. It is not a percent of the watts the motor can deliver, because even when I set it to 35, I still am able to get 330 watts, and when I set it to 100, I get 330 watts (see above, I should be able to get over 500watts). It seems that is a percent of speed, sort of. This proved to be somewhat handy when I cruised the beach. I found that when I was in mode 1, where I had set it to 35, it would give me more boost when pedaling and my speed was below 16mph. When near or above 16mph the boost would disappear. This was a useful speed limiter. For any value higher than around 50, it made no difference. 6) The modes seem to be a speed control, which is useful, but not a boost control which would also be useful. There is no way to tell it that you want X watts of boost when pedaling. That would be a very useful tool to have when riding at extreme range. On my journey to and from that store, it worked out well that it only delivered 330 watts when I pedaled, because I would have run out of battery had it delivered more. However, at the time, I was in a panic that I needed to drop it down to say 250, but I could not. I am also unable to get it to deliver the advertised 500 watts when I pedal. 7) The manual is high comedy. It seems like they used google translate to generate the english version. They have a USA distributor, why not give them the english source file and ask them to eliminate the comical sentences? In the process of discovering the above lousy software I would review the manual and find nothing to explain how these modes and other settings are supposed to work. But this is reasonable. Nobody would write "You can choose between N different mode sets so that, so that, ... um, we don't know why anyone would do this, but golly gee, you can!" Did the software developers actually ride the bike on a real journey? I doubt it. I don't think they ever rode this bike on a fun trail with ups and downs. I don't think they ever used this bike to get to some destination and back. If they had, they should have discovered how dumb their software design was. I pointed out all these failings to Rattan. After several exchanges between us, they offered to make a new version of the software and send me a new control module. I readily agreed. I sent them my opinion of how the whole thing should work. It has been almost a month now, and I have not heard back from them. I do not expect a new module this soon, so I have not given up hope. When I do receive a new module and the software is at least as good as I outlined in my design spec, I will eagerly update this review. I will be thrilled with their customer support, their willingness to improve, and will sing their praises. Until then, I-PAS is NOT a selling point. It is a problem.;;Reviewed in the United States on April 9, 2020;;3.0 out of 5 stars;;Lousy software;;John Taves;;;Overall the bike is great but there are a few items that need to be addressed. The chain in low gear rubs on the fat tire. The handlebars are not exactly lined up with the front tire. And when in peddle assist the bike keeps going under its own power after you stop peddling for a few seconds ,which could be dangerous if you were trying to stop, and the bike was accelerating. (When you apply the brakes it does stop the motor). Despite the few needed changes suggested above I would still recommend the Rattan bikes as they fold up easily, they are a good size for both me (6’ 1”) and my wife (5’6”) and the battery holds up well.;;Reviewed in the United States on March 12, 2020;;4.0 out of 5 stars;;Great folding E bike;;Damon Newsom;;;Bike arrived with the wrong motor. 350 watt not the 500 that was advertised.;;Reviewed in the United States on April 8, 2020;;1.0 out of 5 stars;;Inaccurate description, not 500 watt;;Jesse Fetterman;;;This is my first ebike. I wanted something for camping. This bike is great on trails with the suspension. It gets me out around my neighborhood with lots of hills. It’s quick in flat areas. Not blazing fast uphill, but I can easily pedal uphill in places I would normally have to get off and walk. Mine came packaged up nicely without damage. It’s basically assembled out of the box.;;Reviewed in the United States on March 5, 2020;;5.0 out of 5 stars;;Fat bear plus!;;MS;;;Glad that I spent a little more to get this bike over some of the cheaper ones out there. One can really feel and see the quality in this unit. If I had to come up with anything I would change it would be to have a little more horsepower at the motor. This is not so say that the bike is under powered, it is certainly fine for everyday riding and is powerful enough to exceed the speed limit for E-bikes in this area. Also, the battery charger could be a little better. The display is also really nice and visible in most situations. The battery is lasting really well, and the regenerative charging is working fine. As stated, overall I'm really happy with this purchase.;;Reviewed in the United States on June 1, 2020;;4.0 out of 5 stars;;Really happy with the bike...;;TriumphRider;;;Fun fun fun. Riding with I-Pas got and throttle combo got me 45 miles easy.;;Reviewed in the United States on May 6, 2020;;5.0 out of 5 stars;;Well worth it.;;Devin

Before I stated there were only 3 options with limited speed. Come to find out, the speed controller is highly programmable. You can pick the number of pedal assist "gears" you'd like ie. 0-3, 1-3, 0-9, 1-9. In addition, you can indicate the percentage of battery output to each gear. Also, you can adjust the maximum speed of the bike.

Lousy software
I think the bike hardware is OK. The brakes feel great, but the rear squeals when applied either hard or soft. The rear wheel spokes crackle and pop as I ride or coast. The left pedal pops under my foot on the up stroke. The full suspension and fat tires are very nice. I have ridden on a sandy beach, a rocky beach, up and down mountain trails, and I have no complaints about the bike's ability to handle everything. But that's what a full suspension fat tire bike should do and can do. The software is horrible. I am a professional software developer. I run my own software consulting company, so I can spot lousy software a mile away. In no particular order: 1) The % battery indicator is comically bad. One time the bike shut off. I pedaled back to my RV and plugged it in and as soon as it booted it showed 46% on the meter. So, should I assume it shuts off somewhere around 40%? After that I took it on an arduous 26 mile round trip trek to a store. There was 1000 ft elevation change from start to the turn around point. I went through dry desert wash with plenty of soft sand, then on lousy roads that shook the hell out of my RV and also the bike, then on OK city streets to the store. There were plenty of ups and downs. The gauge showed 100% for the first 2/3rds to the store, which was mostly downhill, but also against a 20mph wind. I was pedaling downhill to overcome the wind. Then it fell like a rock to around 70%. I was in a panic in the store because I figured it would shut off going up hill on the return at around 40%. On the return up and down city streets, and up a very long stretch of road that was a pure up hill climb, it hovered around 70%. Anytime I pedaled it was using an indicated 330 watts, and I was always pedaling when not going down hill. I knew I was draining it. The last 4 miles were on a horrible wash board dirt road that was up hill. The indicator dropped to 45% at the start of that. I was expecting to lose the much needed boost at any moment.... I was constantly checking the gauge just waiting for the bike to die. But the indicator hovered around 45% until I got back. By my calculation, using the indicated 330watts, I estimate I used 450watt hours of juice which is damn close to the expected 500 watt hours of the battery. In other words, I drained that battery. A battery indicator that basically has 3 values (100%, 70% and 45%) but pretends to give you 100 values is hideously bad. It is obvious that they are only measuring the battery voltage, which is just plain dumb for a lithium battery. They should measure the watts over time and report that. 2) The thumb throttle only works when you are not pedaling and when the mode setting is set on a boost mode. This is silly. Just make the throttle supply juice to the motor whenever it is pressed. There is no excuse to make the user plop the pedal assist thingy into some arbitrary number to make the throttle work. Additionally they should adjust the gain on the throttle so that the boost is linear across the range. It feels like all the boost occurs in the second half of the throw. 3) When pedaling it only delivers a maximum of 330 watts of boost. If I stop pedaling, and go full throttle, it indicates over 500 watts. (I believe the watt indicator, if you go full throttle, then rotate the pedals without putting muscle into it, the boost obviously drops off matching the watt indicator.) What is this nonsense? When you go up a steep hill pedaling with all your might, you want all the boost you can get. I paid for a 500watt bike. I want the full 500watts when pedaling! 4) The regeneration is useless but it should be very useful. We don't buy an e-bike to generate electricity, we want to capture wasted energy when we need to slow down. The user interface should be just like a brake, because that is what regen is. It is a brake. It is not a strong brake, but I would use that regularly as I check my speed on steep down hills. That is not possible on this bike because you have to use the more cumbersome + and - mode buttons to get into mode 0 to generate. I rode on some fun roller coaster trail, but there is no chance of using regen on the down the hill sections, because it will take too long to flick back on the mode that will do boost for the uphill section. You have to get the mode thing back to non-zero in order for either pedaling or the thumb throttle to supply boost. Plus you cannot modulate the regen, so you cannot modulate this brake. (Note: I suspect that the motor does not have permanent magnets and thus it cannot generate unless the speed is above 16mph, and thus even with the best user interface it will not be very useful) 5) The modes are just plain stupid. You can select from a variety of mode sets in the "advanced" settings. A mode set is, for example, 4 different values of pedal assist. In the advanced settings you can tell it how much boost in mode 1, and 2, and 3, then repeat this for any number of additional mode sets. Why anyone would want multiple sets is beyond my comprehension. Furthermore, the boost is a number from 0 to 100 that has no meaning. I assume it is a percent, but a percent of what? I don't know. It is not a percent of the watts the motor can deliver, because even when I set it to 35, I still am able to get 330 watts, and when I set it to 100, I get 330 watts (see above, I should be able to get over 500watts). It seems that is a percent of speed, sort of. This proved to be somewhat handy when I cruised the beach. I found that when I was in mode 1, where I had set it to 35, it would give me more boost when pedaling and my speed was below 16mph. When near or above 16mph the boost would disappear. This was a useful speed limiter. For any value higher than around 50, it made no difference. 6) The modes seem to be a speed control, which is useful, but not a boost control which would also be useful. There is no way to tell it that you want X watts of boost when pedaling. That would be a very useful tool to have when riding at extreme range. On my journey to and from that store, it worked out well that it only delivered 330 watts when I pedaled, because I would have run out of battery had it delivered more. However, at the time, I was in a panic that I needed to drop it down to say 250, but I could not. I am also unable to get it to deliver the advertised 500 watts when I pedal. 7) The manual is high comedy. It seems like they used google translate to generate the english version. They have a USA distributor, why not give them the english source file and ask them to eliminate the comical sentences? In the process of discovering the above lousy software I would review the manual and find nothing to explain how these modes and other settings are supposed to work. But this is reasonable. Nobody would write "You can choose between N different mode sets so that, so that, ... um, we don't know why anyone would do this, but golly gee, you can!" Did the software developers actually ride the bike on a real journey? I doubt it. I don't think they ever rode this bike on a fun trail with ups and downs. I don't think they ever used this bike to get to some destination and back. If they had, they should have discovered how dumb their software design was. I pointed out all these failings to Rattan. After several exchanges between us, they offered to make a new version of the software and send me a new control module. I readily agreed. I sent them my opinion of how the whole thing should work. It has been almost a month now, and I have not heard back from them. I do not expect a new module this soon, so I have not given up hope. When I do receive a new module and the software is at least as good as I outlined in my design spec, I will eagerly update this review. I will be thrilled with their customer support, their willingness to improve, and will sing their praises. Until then, I-PAS is NOT a selling point. It is a problem.

Great folding E bike
Overall the bike is great but there are a few items that need to be addressed. The chain in low gear rubs on the fat tire. The handlebars are not exactly lined up with the front tire. And when in peddle assist the bike keeps going under its own power after you stop peddling for a few seconds ,which could be dangerous if you were trying to stop, and the bike was accelerating. (When you apply the brakes it does stop the motor). Despite the few needed changes suggested above I would still recommend the Rattan bikes as they fold up easily, they are a good size for both me (6’ 1”) and my wife (5’6”) and the battery holds up well.

Fat bear plus!
This is my first ebike. I wanted something for camping. This bike is great on trails with the suspension. It gets me out around my neighborhood with lots of hills. It’s quick in flat areas. Not blazing fast uphill, but I can easily pedal uphill in places I would normally have to get off and walk. Mine came packaged up nicely without damage. It’s basically assembled out of the box.

Really happy with the bike...
Glad that I spent a little more to get this bike over some of the cheaper ones out there. One can really feel and see the quality in this unit. If I had to come up with anything I would change it would be to have a little more horsepower at the motor. This is not so say that the bike is under powered, it is certainly fine for everyday riding and is powerful enough to exceed the speed limit for E-bikes in this area. Also, the battery charger could be a little better. The display is also really nice and visible in most situations. The battery is lasting really well, and the regenerative charging is working fine. As stated, overall I'm really happy with this purchase.

Love the bike
This is my third ebike. The packaging of the bike during shipment was poor. I received the bike with some damage. In particular, the gear shift indicator was broken. After opening the box it looked as though the bike was packaged with whatever packaging material they had laying around. The bike definitely was not secure inside the box. I bought the bike particularly for it's compact size, folding capability and FULL suspension. The ride is fantastic. At 245 lbs, this bike can handle my size with no problem. It has good acceleration and a top speed of 28mph. There are only 3 pedal assist settings to choose from. Speed 1 is 18-20 mph, speed 2 is 23-25 mph and speed 3 is 28 mph. It would have been nice to have a setting for a lower speed in addition to a cruise control. The battery life has been moderate so far, I haven't done a full range test yet. Overall, I'm currently pleased with this Rattan Bike. Update 02/19/20 Odometer is currently 62 miles. So, the battery life is "meh" running throttle only. I'm currently looking into paralleling another battery to increase my Ah. There is a BIG correction on my part when it comes to the pedal assist. Before I stated there were only 3 options with limited speed. Come to find out, the speed controller is highly programmable.
