UCAN2 BMX HANDCYCLE DIY PLAN
Using extremely durable 20 inch BMX wheels, this hand powered trike will be virtually indestructible. With a capacity of over 400 pounds, you can take your handcycle on or off the road, and it will handle anything you can throw at it.
The square tube frame easy easy to cut and weld, so even a first time builder will be able to create a great looking DIY handcycle. You can salvage the steering components from an old BMX bike or purchase new parts from any bike shop.
All of the transmission and braking systems are placed in the front as a self contained unit. Braking is achieved by pedaling in reverse, the harder you press, the more the brakes are applied. Riding this hand powered trike is as easy as riding a refular bicycle.
You can adjust the cranks so both hand pedals are inline as shown here or place them apart like they are on a regular foot pedaled bicycle. Both configurations work well, and it is easy to adjust to inline or offset pedals by removing only a single nut on the crank axle.
The chain is routed over the front forks using a standard hardware store pulley, and the idler is made from an old road bike derailleur. The transmission system is very smooth and it is impossible to derail the chain, so this DIY handycle can be ridden hard.
The seat support utilizes a standard bicycle seat post tube, so a standard bicycle seat can be used. The seat can be adjusted up and down just like a regular bike, and you can easily add a much larger seat for riders that may require some extra support.
The foot support system is designed to allow feet to be held in place using belts or straps. You can easily modify the foot supports to suit your riders requirements. The drive system also includes a chain guard to keep loose clothes out of the chain.
Carrying one or more passengers is no problem at all for this sturdy DIY handcycle, so you can give your buddies a ride to the park or tow them using a rope on their skateboards. Atomic Zombie’s easy-to-build DIY handcycle is as good on the road as it is off the road, so there is no terrain that cannot be conquered by hand power.
