So far I have not had problems with the bike. The battery life exceeded my expectations.
- very lightweight
- very robust
- strong motor
- good gearshift
- recommendable torque sensor
The delivery was good and it was not damaged. Easy to put together though a you tube guide for the mud guards was helpful. Great fun to ride and lots of power to get up hills. Having the battery in the seat post is good because if I lock it up when I am out I remove the seat post and take it with me.
I bought this bike to be more green. I love the way it drives. With and without batteries. I had a minor issue but their customer service is helping every step of the way. I love this cargo bike, and for the money you can’t do better. Thanks for a cool product
My e-trike is so much fun! I’ve had so many people ask me about it.
I can run so many errands with it - forget the car!
Love my bike! It was simple and easy to put together. I use the throttle to start off rather then peddling to start as it’s easier and I can control the speed better.
The EUNORAU FAT-HS Fat Tire is hefty but fun. Great for commuting and moderate single track riding. Zoom provided responsive service.
I love the bike,it rides great. I have yet to really push it but so far so good. Zoom bike has been very professional. I'm satisfied all the way around
I want to thank Zoom for a great bike , very easy to assemble. I find myself waiting for the next opportunity to venture out on my e bike. I’m a middle aged man so I can appreciate the ride this bike offers. A+
Wish I could picture but it’s all decked out and hunt ready and can carry ALOT of weight.. it’s a work of bike art and a true blessing to own!! Thanks 🙏
Great ebike for the price and so much fun riding to the beach. Great value!
Extremely satisfied with purchase of The Revi Predator.. I have put it to a moderate test as a novice rider.

And Assemble within 30 minutes.. Tools required were included, Before first ride.. Insure handle bars are correctly tighten. fork nut was Lose as I made my first voyage. simply tighten. I recommend the product and Store and can validate satisfaction.
The electric bike is so fun to ride... Only issue is instructions and putting it together
This bike is solid and very convenient in all aspect. The price, the power, and the comfort is unbelievable. I ride a lot for fun and I also ride to work sometimes and it is always comfortable. After logging so many miles on it looks like new!
I've had this bike about 4 months now, and it's made my life so much easier, especially now that I can use it for trips that I used to take public transportation; was never a fan of waiting for the bus. Also, fyi a speedometer sign clocked at 22 mph. One drawback is that the front brakes were not "plug and play;" they dragged; I didn't have the skills to adjust, them so took them off; had to have the bike mechanic reattach them. One more drawback that surprised me: I live in Chicago, a big city, but I was lucky because THE LOCAL BIKE REPAIR HAS THE ONLY MECHANIC IN THE CITY WHO WORKS ON ELECTRIC BIKES. Another mechanic said he and his colleagues are wary of them because the components are not standard; they vary depending who the manufacturer is.
