Motor
UniSA originally used an Advanced DC 6.7-inch series-wound brushed DC motor, but it was too powerful and too heavy.
Team Trev replaced the original drive system with the rear swing-arm assembly from a Vectrix Scooter. This included a motor with 7 kW continuous power and 21 kW peak. It was easy to install and had enough power, but we could not find a low-energy car tyre to fit the forks and it has high unsprung mass. (Vectrix want broke in 2010, but have since been revived.)
We need a small, low mass motor we can mount on the front of the swing arm.
Motor controller
- Semikron. Team Trev used a Semikron IGBT power stage with a custom control stage

Battery
Team Trev used Kokam 100 Ah lithium ion polymer cells. These had good specific energy, but were expensive.
Suspension
Team Trev used suspension from a Can Am Sypder. It would be better to design our own.
Springs and shock absorbers are from motorcycles. (Team Trev is about to try a new set of springs, and will report on the performance.)
Tyres
We need narrow, low-mass, low-energy tyres. The UniSA Trev has Michelin Energy tyres (165/75R14); the smallest width available now in Australia is 175 mm.
