ELECTRIC SUZUKI GSX

The Suzuki was built in Japan in 1984 with a petrol motor and was converted to electric drive in 2000 by students of Queensland University of Technology.

The bike is registered in Queensland and has been approved by the Department of Transport.

Electric bikes are best suited as second vehicles and ideally used for local commuting to work, etc. This bike has a range of up to 20kms, a top speed of over 100kph and can carry 1 passenger plus the rider.

This bike is driven by a 3 kw series DC motor, powered from a 72v (6 x 12v) 28 amp hour Odyssey sealed lead acid battery bank. The speed is varied by a Curtis speed controller. The original motor and gearbox was removed. An E-Meter has been fitted, which monitors the battery voltage, motor current and is also the fuel gauge.

Recharging takes less than 2 hours, with a high current charger.

All up weight is 200 kg plus riders.

The bike was ridden regularly by me.

Nice bike but you could easily double the range per charge if you replaced those heavy lumps of lead with lithium. Image

G'day Ron,
Was the bike certified under anything like the current system with QT? Did you need an engineer? I'm on the hunt for one who has certified a bike..

Giles

The bike was done under the old system, pre engineer approval, when QT did it them selves, in a time when EV conversions were a rarity.

Catavolt is 45-25 = 1.8-1 and on my road bike the ratio is 74-15 = 4.93-1

The road bike is now on ebay
