Motorized Mountain Bikes and Road Bikes Motorize a full suspension mountain bike to get a smother ride or for a little more speed try motorized road bicycles. This section is for sharing ideas on motorizing your mountain and road bikes.

Default Re: First Motorized Bike, what would you do?

I built a staton friction drive on a Phat Cruiser. It would top out at 23 MPH. It has to be dry to work. I swapped out the Mitsu Clone for a Tanaka. It was easy to build and I spent all my time riding and not wrenching. They are worth it.

You could just buy a rear wheel with 36 spokes. They are easy to find and it would probably be cheaper to buy a rear wheel and in frame kit than a FD kit from Statin.

For a first build, the Staton kit is the simplest, bombproof build...
but, as stated by Agreen, slippery when wet. I made a simple improvement
on the drive roller the performs better in the wet, but will eat a tire fast
if you get heavy handed on the throttle. Burning #60 grit emery paper, I
then panned out & dried the grit. I mixed the grit with J & B weld & painted
it onto the roller to a uniform surface. This grips like crazy. Being next down
from diamond in hardness,the emery is a durable surface that doesn't wear
easily. Should mine ever wear, it's easy to mix more paste & reapply.
Engine? I've got a cardboard box full of 'em. Spend the the money & get a
Tanaka PF-4000, a reliable, clean, powerful 2-stroke that is lighter with
fewer moving parts to go wrong. I've a Huasheng I'd give you, but I'm not
that cruel.
If you want a kit that's all weather/all terrain, get a GEBE. I spent hours &
plenty of bucks before building a viable DIY belt drive. GEBE has done the engineering
for you. They are not cheap, nor are the Tanakas, but you get what you pay for.
My belt drive was insanely labor intensive. The GEBE is simple,...BUT you must
read the instruction carefully and not make assumptions. First of all, make sure
it will fit your bike. the info is on their site.
P.S. I would dispute Agreen's statement that 4-strokes have more torque. My
40cc Tanakas will out perform any gx50cc Honda or Huasheng 4-stroke.
