I recently purchased this dual-seat electric bike from Amazon, and it has completely transformed my post-work routine. The sleek, stylish design caught my eye immediately—it looks even better in person! The bike’s powerful motor provides smooth acceleration, making it easy to cruise through neighborhoods or along trails after a long day. The throttle response is quick, and the pedal assist offers just the right boost for effortless riding . The dual seats are a game-changer. My partner or friend can now join me on relaxing evening rides, and the rear seat is surprisingly comfortable with its padded design and sturdy backrest. Despite being a budget-friendly option, the bike feels robust and well-built, handling two adults without any issues. The fat tires and front suspension absorb bumps effortlessly, ensuring a smooth ride even on uneven paths . Battery life is impressive—I consistently get over 30 miles per charge using pedal assist, which is perfect for extended leisurely rides. The removable battery is convenient for charging indoors. Assembly was straightforward, taking about 45 minutes with clear instructions . Highly recommended!

This bike is a great all around bike. The throttle was sticking but I contacted tst and they sent me a new one right away. The bike works perfect now. Battery life on this bike is great, well worth the money, easy to put together and oncw unlocked is a pretty fast bike. The big cushioned seat is great for long rides. I'd buy again.

Front brake a bit sticky which locks down the motor, have to make sure brakes are fully disengaged. Otherwise works fantastic. Daily commutes go well. Works well for a bigger dude with no cargo. Pedaling is a bit difficult due to leg length (5" 9 tall) but I didn't get it to manually pedal. Plenty of charge for 3 mile commute 6 days a week throttle only. Have had a flat since running over stickers, but there was only 1 actual hole after like 10 of them hit the wheel so I'd say par for the course for tire + tube thickness. Get some slime and prefill the tubes or buy pre slimed tubes to save that headache.

A very nice and convenient step thru. I really like the styling. It came with extras I was not expecting such as the hydrolic disc brakes and white lettered sidewall tires, features I would expect in a higher priced bike. Overall quality seems very good. Good performance and lots of fun.

It's been a long time saving up and finding the right e-bike for me, but I finally found it. The seat is so comfortable, and the bike did take time for me to get used to, but I love this e-bike so much. Each pedal assist system has its own range of miles and goes faster by 1 level. It gives you the feeling of riding a motorcycle. It also came in the box very carefully, nothing was bent or broken, and everything works just fine. You can also save the battery life just by pedaling as a regular bike. The assembly team did a great job as well and they went over everything that I needed to know.

The bike was delivered on February 20th. We got it put together the next day and started charging the battery, but it will not charge. The light stays green like it is fully charged, but it is not. We have yet to be able to test the bike itself, to see if the motor etc. is in working order and the window for returning the bike is closing soon (the box it came in says 7 days to return) We called customer service and they walked us through a few things, but it did not help. They had us make a couple short videos about what was happening and email them. We were told they would get back to us in a few days. This bike was bought as a mode of transportation to get back and forth to work, and waiting for a resolution is a real hardship. Hoping and praying for a solution very soon.
