This bike was made by Tallmartin of Rat Patrol UK. If features five speeds, a front disc brake, luxurious scooter seat, and a flywheel-like automobile wheel. No need for a kickstand, this thing stands on its own.
The bottom bracket is a BMX handlebar. Then just find a piece of rod that fits and weld on the crank arms.
No bearings in the rear wheel, just a slot where it's held in by cotter pins.
Here I am cruisin' with some scotsmen.
Yes, Tallmartin is insane. But then again, we knew that already:
