For
a short ride to the bus stop and short rides to the shop or office,
all you need is a single speed bike with 16” or 20” tires. The
smaller the drive wheel, the lower the gear is, but try to find one
with room for 2.25” wide tires. And use a simple voltmeter on the
accelorator, a lot cheaper than a fancy CycleAnalyst. There is a MINI
CYCLONE mid-drive kit
that I want to install on a single speed folding bike. But a 2000
watt direct drive hub motor could work on suach a light weight bike
as long as you don't need to climb steep hills with cargo. Just be
aware that hub motors weight a lot more than mid-drives.
It
would be good to build a folding mini electric motorbike simular to
this
one,
With room for 2.25” x 20” OD [16” rim] motorcycle tires. I
believe all bikes should be made Heavy Duty no matter how small.
