Great Choice ! Fast shipping. Simple to install. In my opinion the best add on kit out there. Gives you power when you need it and standard pedaling when you don't. The Sprinter is a great choice for converting cruiser and vintage bikes like ours.

We're obsessed with our Hilltopper Discover e-bike! We couldn't be happier with our Hilltopper Discover step-through electric bike! We use the bike daily for hauling our toddler to daycare. Our previous electric cargo bike was way too heavy. Being able to throw a child seat on the back of this relatively lightweight e-bike has been a game changer. My husband (6'2") and I (5'4") are both able to use the bike with a simple seat height adjustment. The folks over at Hilltopper were super friendly and helpful. We would highly recommend their products to anyone that's in the market!

My wishes were never met My wishes were never met! I wanted a second battery to replace my failing one, that way my range is extended plus I will not be stranded. The first person sold me a complete battery/carrier set up but the set up was mismatched. The second person straightened this mistake out but I still have my old battery/carrier set up and it is incompatible with the new carrier/battery. Now several months later I'm tired of working with these guys.

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!

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!
