now for a serious question.
If a kid's trike can be pedaled from a crank built into the front wheel, and if you were going to build a miniature good humor trike, could you put a crank on the front fork inside the wheel.
Then use one of my hang on motors as a drive motor. and the box under the seat to store the batteries. Use it for parades and such. Not touch the front wheel pedals often but have them available to keep it in the bicycle rules and out of the moped rules.
I very, very seldom use my pedals now on the faux trike except maybe to start it at the very beginning. Maybe use a front wheel like this one.
URBAN X STREET MONSTER BIKE TRIKE BIG WHEEL TRICYCLE - eBay (item 390116227557 end time Nov-13-09 20:52:09 PST)Sixteen inches on a twenty inch bike frame, to rear wheels from a sixteen inch bike, using the coaster wheel with one of my 600 watt hang on motors running at 900 watts.
The problem with a do it yourself trike has always been the pedal drive system, what if you just used a front wheel crank and a rear wheel drive system only. No rear chair or sprocket except for the motor hanging on one of the rear wheels. I wonder if a one piece crank would fit inside and emptied out coaster brake wheel.
Now you have me thinking again a dangerous thing...
