Euroscooter to drift trike.

I came by a mobility scooter on the cheap ($20)...

http://euroshop.mybigcommerce.com/euro-scooter/

The wires cut, so I just had to reconnect the phase and hall wires and get a new key...

I cut down the fork and seat, and welded on some foot pegs to make a drift trike. Obviously, the governor wire had to be disconnected.

Nothing like an adult power wheels to make an old, grown man smile like a kid!

And if the cops try to bother you, you just tell them it's a handicapped mobility scooter, protected by ADA rules.

Try it out in the local mall :twisted:
 
When life hands you lemons, make limoncello.
 
Just picked up another mobility trike. Amazing how many people scrap these things when their crappy lead acid batteries go bad...

Time to start making a companion drift trike...
 
(Edit to reflect that I'm not using original hub) the hub that came with the new euro scooter was rusted together and may never run again. I picked up another ebike hub used locally. It does not turn easily by hand. I hooked it up to a speed controller and it will turn, but not smoothly at all. I took the side of the hub off to see if there is any rust, but it seems like it is all pretty clean. What mechanically do I need to look for that would explain ratchety behavior on the wheel?

Does it turn smoothly by hand without power?
 
No. Extremely difficult to turn even with a wrench.

The wheel had the wires insulation destroyed where they exit the hub so I pulled them into the hub and wrapped them with electrical tape. Reassembled and then it won't turn.

All of the phase wires are disconnected and not touching each other.

I have felt Cogging before from phase wires touching... this feels like mechanically something is stuck in there...
 
Best guess is either:

--some bit of something fell into the stator/rotor gap after the repair, physically jamming the motor.

--the phases are still shorted together via the phase wires somewhere, probably inside the motor, or the axle. If the problem did not happen immediately after reassembly, but only after some time spinning, then the wires probably rubbed on the side cover until insulation wore off, and are now shorting to the cover and thus to each other.


--much less likely, but if the bearings recieved too much side-load removing or reinstalling the covers, they could be mechanically damaged and jamming.
 
Faceslap... :roll:

I forgot to mention the little issue that I tried putting on the side walls from a different hub that has a drum brake built in.

The screws lined up perfectly, so I thought I was in good shape.

Turns out the inner diameter of the bearings is 2mm larger than the original... allowing the magnets to pull the stator to one side.

So I either need to find 6203/15 bearings, or find a way to add a different brake...
