A bike and a scooter had a 3-speed child.

Nope sorry, I think thats it for the picks.

It is low and small, and it does represent the beta version. This was constructed with a cheap scooter and off-the-shelf parts.(other than the tranny mount the system bolted together)

The final version is on the drawing board and will be an entirely custom built frame that would suit taller riders, longer wheel base, room for larger rear scooter wheels up to 16" I hope, and a taller seat height from the ground for leg comfort and safety.

Glad you like it.

I am considering to attempt mounting a tricycle wheel on the front that has working peddles, which reclassifies it in my town as a motorized bicycle. The advantage of the M.B. classification instead of the current Foot Scooter class is legal right of way on streets with speed limits up to 35 MPH. as a foot scooter, I am limited to streets with a speed limit up to 25 MPH.

btw, With my 135-140 lbs weight, the machine tops out around 8000 rpm / 40MPH in third gear.

Currently Im exploring some cog swaps and rear tire size with this tool.

The default settings are what I have installed on the machine.

You sure about that being freewheel? It looks more like a unicycle wheel.

It defiantly would not mount to bicycle forks.

Swapped back in the 21 tooth cog, topped out my tires, removed the generator dynamo from the front wheel, and tucked hard.


Finally beat the 40 mph barrier!

41.80 MPH @ 7765 RPM

Last setting was 39.9 @ 8100 with a 24 tooth cog.


No peddles!
