    • Great purchase and an awesome bike!
A great reliable bike. I would definitely recommend this purchase if you are looking to get your first E-bike or just a new upgrade.

    • The most useful bike I Own!
Okay, I seriously love this bike. I have an injury that makes riding bikes very difficult, but because this bike is electric it gives me the ability to ride again like never before. It almost feels like cheating it is so good. I can only really pedal with one leg so the bike's electronic motors kick in and help me out massively. The bike rides super comfortable. I noticed the pedals were a little small for my shoes and feet, but that's more of a me issue and I might just have to get different pedals. The cost was super reasonable and I'm planning on getting another one of these. I've got plans to kit it out with like a backpack or storage attachments and probably going to get one of those pull behind things to go with it for the kiddos. Anyways Its really great for making quick trips to the post office and the battery lasts that long and I haven't discovered how long the battery will go but its great so far! The assembly was easy, I'm fairly proficient in mechanical builds so if you are like me it should be fine for you. The shocks keep you pretty comfortable and there's a lot of stability when riding it. I find that it works well as far as function goes. ... show more

    • Win and done lol
Great overall quality craftsmanship with the frame of the body of the bike in general but it is definitely a lot slower than other bikes comparatively speaking. I just think I should have shopped around a bit more and spent a little more money 🤑

I'm 63 years old and 5' 2 for reference. Seat goes low enough that I have no problem touching the ground with my feet and staying steady while sitting when stopped. Happy so far with this bike for the price. It's my first time with an e-bike. I've had it a week and am enjoying the peddle assist. I still get exercise but I don't want to give up after a mile. I live on an island and now can't wait to explore all the great trails we have here. Easy assembly (per the BF). The only drawback for me, hence 4-star rating, is I find the seat extremely uncomfortable. I have a new, bigger seat arriving today. ... show more

    • Good bile for the price
It has speed as stated (20 MPH pedal assist and 17 thrust only), installation was vary basic, it has a good build. The only problem it is not very comfortable around tough terrain because it does not have shocks absorbers.
