Absolutely best thing since sliced… Absolutely best thing since sliced bread installed on 2019 cannondale adventurer The hilltopper is perfect for me easy to install works as advertised does exactly what I need just a little help on the hills at 65 I still like to bike but some trails have hills this system works well I don’t use pedal assist throttle only I have been over 250 miles from install battery still fully charged Company is great to deal with no issues to date customer service followed up after my order was completed to make sure all was good

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.

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.

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.

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
