EV conversion kit is working fine on my mountain bike I have been using my EV converted mountain bike at least 3 or 4 times a week for pleasure and workout. I'm relying on the EV parts as I am out of energy going uphill in Boulder Colorado. I am happy with the Hilltopper conversion kit on my mountain bike and it is working as I expected. By the way, it was easy to replace the flat tire in front of my mountain bike with the motor in front. I'm planning to convert my other bike to EV conversion too in a few months. Great job guys

We needed a brand new battery for our… We needed a brand new battery for our Hilltopper but we had the old water bottle style battery. Our representative at Hilltopper found one of the last ones available, tested it over the weekend to make sure it was in great shape because it was in the warehouse probably for a long while and sent it out in a timely manner. The battery is wonderful! We own two hilltoppers bike kits so far and it is an amazing product and at an affordable price point!

SECOND REVIEW Wrote a five-star review when I first got the Hilltopper kit. Have enjoyed it now for a few months, and would definitely encourage anyone wishing to electrify their bike to purchase one. Easy to install, easy to use, and it makes an ordinary bicycle far more versatile and a lot more fun.

Best Electric Conversion Kits Anywhere! I purchased 2 Hilltopper Sprinter kits 3 years ago; they still perform like new, after that amount of time and approximately 300 miles of riding. I just purchased 2 more Sprinter kits; we are now retired snowbirds, and I’m tired of lugging our bikes back and forth. So now we have electric bikes at both houses, and continue to bike year round. Absolutely awesome products and support!

The diameter of my handlebars is larger… The diameter of my handlebars is larger than the throttle mount. Had to modify it a longer screw and then wedge it so it doesn’t slip gorilla glue. I hope it works so far it’s worked great. Hilltopper was very simple to install and so far seems to work really nice Back-and-forth to work when the weather is good 2 1/2 miles each way it’s really nice full suspension specialized bike ground control
