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

We love our Hilltopper Sprinter motor… We love our Hilltopper Sprinter motor assists. Being able to get up hills will help us complete the American Discovery Trail in West Virginia. I was disappointed that the bike center found the battery cradle to be defective on my husband's Sprinter and that my husband wasn't able to use his our first week in West Virginia. Staff were responsive and sent a replacement. However, the lag time between responses to emails and phone calls was frustrating. I had hoped they could overnight the part in time for our trip but instead didn't hear back until we were half through the trip. Hopefully they will be able to improve response time in the future.

When I arrive to a steep hill When I arrive to a steep hill, my hilltopper saves the day by making my climb very comfortable. On flat roads, using my hilltopper make me pass bikes that are much lighter than my bike.

Poor technical assistance I’ve been using a Hilltopper on 2 bikes for 4-5 years. Loved the product. This year I bought a battery upgrade. Installation was less straightforward and getting support was impossible. There are no instructions and the only help that I could raise on the phone were non-tech people and robots.

Great addition to our old trike. You made our old pedal trike a very nice e-trike for us old folks (77&81year olds). First off I really enjoyed putting the upgrade on the old trike and we both enjoy talking it out for a ride, if we get tired it will take us home with out any more pedaling.
