Mixed results with the Summit kit. I bought the Hilltopper Summit kit. The documention was not accurate and incomplete. The kit met my needs but not my expectations. The way to reset the trip counter is not obvious and their tech did not know the proper way to do it. There are several features that the display is capable of but not implemented. I expected more of their top of the line kit. The display was initially defective but their tech was good about sending another one. The throttle has a dead zone and it is difficult to control the power.

I own a 2005 3G single speed beach… I own a 2005 3G single speed beach cruiser,which I love. Wanted an assist for long flat beach rides but didn’t want a multi gear new e-bike. Researched and found the Hilltopper kit. 1/2 hour for kit installation and I was riding a motor assisted bike. Some more time later to switch out tire,see Hilltopper YouTube,organizing wiring and permanently installing the battery. Ez-Over did not have water bottle anchor holes. Hit 20mph on flat beach. Made a 45 degree driveway much easier with me peddling. Very happy with conversion kit as opposed to buying a new bike. This kit seems perfect for flat crushing and occasional hills with pedaling help. Battery charge longevity,yet to be determined but I did ride 10 miles at 10mph with only motor and had no problem.

Really enjoying my Hilltopper electric… Really enjoying my Hilltopper electric conversion kit. Fast shipping. Easy to install. And- most important- timely responses to my questions via email. This little unit packs a punch and helps an old timer like me get out and bike despite aging muscles and nagging arthritis. Highly recommended!

Freedom Being a Retired Disabled Veteran I never left the Senior Apartment Complex Until I installed the sprinter Hilltopper Kit.. 1st week I rode 24 miles in 1 day .. to see it’s limits.. now I normally ride 5-15 miles every day.. depending on the scenery.. Thank You For Giving Me the freedom to move about again… Dennis

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.
