First one would go to my mother. ...
She might call me up from 300 miles away and say she can't get back home.
She forgot to take the charger, to recharge, for the return trip.

Do those need to be powered down between direction choices?

greenerwheels wrote:Yeah you could build a serious torque monster with one of those! There maybe more work involved in making it work, but being able to control the gear ratio (top speed) would make for a safer and better hill climbing ride. What kind of life would you get out of one of those brushed motors?

"Schwinn Meridian Adult Tricycle", Front hub motor would work, but I prefer the re-gearing ability of the EZip gear motor.
I've had many requests as mobility devices for nearby Senior housing project.
Also, without the "need" for pedaling, a big comfy seat can be dropped down, further lowering the center of gravity, thus, enhancing stability.
Foot platforms w/outrigger skid pads, or "training wheels", could be added, for additional turning safety, in "Mobility Device" application.
Beats paying $2000-$3000, or more, for other "mobility devices".
Plus the bonus of higher speed, and a cargo basket, for runs to the grocery store, etc.
As a Mobility Device, crank, pedals etc. could be removed. This would allow the simple addition of floorpan, for setting feet on. The big advantage is that the EZip geared motor could be directly connected to the rear axle, and would act as an effective braking system, when throttle released! Making a regen controller feasible?
