Bests & Worsts Reviews from Amazon

This is awesome! I used this for a custom made handicapped electric bike for wheel chairs. It is silent, and most people don't even realize that it is electric. The install took about 4 hours only because it was a custom bike and I extended the wires for the controller. I am not using the pedal sensor, just the throttle controls. Keep in mind you may have to move your gear shifter to the opposite handlebar and mount it upside down if you have a rotary shifter. I am using Powersonic PS-12120F2 - 12 Volt/12 Amp Hour Sealed Lead Acid Battery with F2 Terminals that fit perfectly inside the bag. I mad a plywood base for the batteries and secured them with gaffers tape to keep them from shifting. Because the batteries bag is removed often I added a BaiFM 50A Battery Quick Connect/Disconnect Wire Harness Plug Connector Kit Winch Trailer to easily take the battery pack and charger for charging. I choose this charger 48V 3A automatic e-bike, scooter & vehicle battery charger that also fits inside the bag wired directly to the battery terminals. This has been good for hours of casual riding for both the caregiver and child/adult. The video shows the first time my neighbor took his son on a ride. The bike will go much faster, however it should be obvious why I have the speed limited to 8 mph for safety reasons. This bike has 3 disc brakes setup as well.
