Hi Paul,
wheel chair hubs are also great for trikes. I have a pair from
Sturmey-Archer, that come even with a drum brake.
The drum brakes are great because you don't need to build the frame to
support mounting points for cantilever sockets!
Regards
Gerald

Hi all
3/8" axles are 9mm [ ish ]
When building trikes , [ like my Python ] and you want to hang a wheel from one side only the wheel of choice is a BMX wheel with a 14mm axle they are 9/16".
These are referred to as 14mm axles on this side of the pond , I must admit to not having heard or seen 9mm axles , however the 14mm are reasonable easy to get hold of.
I think a adult 3 piece crank/pedal uses a 9/16" pedal axles although I cannot screw a BMX 14mm axle into one it would only take a little filing for it to fit and be locked with it's wheel nuts to the crank arm.

The front wheels that I used only has 5/16" axles, from cheap kids bikes and probably too weak to mount directly to the crank. How are your 3/8" axles holding up?
Maybe the 1/2" pedal axles are overkilled. I will look for some wheels with 3/8" to try.
Thanks

Hi James S
I am interested to see your set up also. You can submit small photos 150kb or less. On my kiddie-wheel set up the wheel bearing balls sit on the inner pedal cone and does not fit too well. The wheel cone can be used without modification but if the hole is big enough for the pedal axle...
Thanks,
Vi

James,
All you need to use are 4 wheel bearing inner races, two on each side to attach to the pedal hole. The tapered side on the race will self align in the pedal hole, no extra parts/machining needed. Contact me for a photo. I have this setup on an MBB bike and if you use it in the 90 degree you will get free suspension.

I am planning an Ilean rear end for my existing Python. My question is about connecting the cranks to the wheels. Rather than weld, I would like to use a Helicoil type of device to reduce the crank hole so that it fits the wheel axle. Any suggestions would be appreciated. Thank you. Jim Wells
