The new parts that I got were all… The new parts that I got were all upgraded. With additional advantages like variable speed, Great voltage more power, and docking station for battery with LED display.

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.

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.

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.

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.
