Of course, still in the offing is an etrike conversion. Schwinn Meredian with eZip motor added. Nice cargo space and hanging big SLA batteries below the rear axle will greatly increase stability.
"Schwinn Meridian Adult Tricycle", Front hub motor would work, but I prefer the re-gearing ability of the EZip gear motor.
Rear freewheel:
16T=20mph
18T=18mph
20T=16mph
22T=14mph
etc.
I've had many requests as mobility devices for nearby Senior housing project.
Ballast!
The main complaint on these bikes is the risk of tipping.
10lbs of li-ion helps very little, compared to the 60lb, of comparable SLA.
And ... I get the SLA for, nearly, free.
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?
Also, I have been recycling 35ah SLA batteries, from the same seniors, using the BatteryMinder rejuvenation process, fairly good success rate of restoring battery capacity-capability.
