$10 Razor E100 Scooter Project Day 1: Rear Wheel

This afternoon I learned of the recently- (?) opened Deja Vu thrift store in Newton and made my first purchase: a Razor E100 scooter in considerable state of disassembly. I’ve long thought that electric scooters looked like fun …

Pieces of Razor E100 electric scooter

All of the wires are cut, the deck is missing, the rear wheel was unattached, naturally the drive belt was missing, and no charger.

$10. I bought it. Sounds like a fun project, eh?

The battery and speed-control bucket could use some repair but seems at least functional. I started working on the batteries but as soon as my brother was available redirected my attention to reattaching the rear wheel.

The rear wheel is belt-driven and needs to be positioned to align with the motor pulley but the spacers were absent and it slid freely from side to side.

Cutting a roll pin

A trip to the hardware store resulted in a roll pin with ID slightly larger than the 1/4″ axle diameter and length slightly greater than the two spacers needed, for $1.89. Then my brother’s giant chop saw made short work of creating two pieces from one.

Touched up a bit on the bench grinder, ends rounded over with a file, and interiors cleaned out with a round file, spacers fit perfectly and the rear wheel bolts on securely. We “kicked” our way up and down the driveway and are eager to get the scooter powered up.

Next: Battery investigation.

    You should begin with checking if the motor works. I found a similar e-scooter in a local junkyard a few years ago. The motor spun but had really low torque and when I opened it up I found that some of the windings were burned out. The overall build quality of the scooter was also very low so I never bothered to repair it.
