I was very impressed with the kit and installed it without any hitches. The instructions were clear and everything does what is supposed to do and fitted together well. Now I'm zooming round on my old mountain bike with ease! I also like the fact I can easily return it to a non powered bike if I want to in the future.

TOP: incredible upgrade. I'm 57 and now to go and comeback at work is simple with my bike, specially when I have to climb elevate points along the path. The best for bike DIY.

Really impressed with the motor kit we fitted to our MTBs. We live in a hilly area and they have enough power to get up the hills. Used them in the Brecon Beacons too - off road! The batteries are small and there is a technic to conserving energy.

I'm happy with my bike conversion kit - it transformed my regular bicycle into an electric dream. The battery is compact yet powerful. Installation was tricky though especially on any non-standard bike, and could use some more in depth instructions included. But no issues since installing it. It's perfect for busy London commutes and allows me to feel more confident riding in traffic as I can accelerate quickly with the thumb throttle. Definitely worth the investment if you're looking to extend your cycling range without buying a completely new e-bike.

it's a great budget friendly electric bike conversion kit it you wanna add a little extra umph to your ride. A did a non-traditional install by adding this to my kickbike. Makes my commute to work much easier. I normally park in an economy lot and either bike or take shuttle to work. For the distance I plan to use this kit for, the kit provides everything I need. Ni, you’re not gonna be carried up the hill but that’s not the point with this kit. It’s to help you get up those hills. For those looking to upgrade kickbikes or other scooter style bikes, this is probably the best option out there since it provides a throttle and no pedal attachment is required. I used to be a bike mechanic, so my warning to anyone looking to purchase is to please, please, please read the FAQs and while installing to definitely following instructions. One thing I had to compromise on was how I talked the water bottle holder assembly. Since the kickbike frame curves, I could only attach one screw to hold down the assembly. The second option was to attach to handlebars, but I was not a fan of adding extra weight to the top end.
