Vehicle Replica Chitty Chitty Bang Bang
- bespoke steel chassis and wooden body. Components taken from a mobility scooter.
Motor Permanent Magnet DC
DrivetrainChain drive to diff on rear axle
Came with the scooter. Fully variable.
Batteries2, 12.00 Volt, Lead-Acid, AGM
2 x 12v 50 Ah Batts - should be good for REALLY long days out!
System Voltage24 Volts
InstrumentationVoltmeter hidden under the bonnet
Top Speed16 MPH (25 KPH)
Too Fast for the littl'un. I need to change the ratio, but I can set the max speed.
AccelerationIt won't wheel-spin in the dry, but on wet grass and in the snow my daughter had a few traction issues!
Range20 Miles (32 Kilometers)
Original mobility scooter electrics had a range of 20 miles on 26Ah Batteries. Chitty doesn't weigh much more, and my daughter weighs just 14kg, so I guess it about the same. We can go driving for 2 hrs with no drop in performance. Now its got 50Ah batteries it should go on all day.
Seating Capacity2 children (one medium sized and one little!), a picnic basket and some teddy bears
Curb Weight120 Pounds (54 Kilograms)
TiresSemi pneumatic
Conversion TimeDon't want to think about it, and I suppose it'll never be finished. S'pose it was about 60 hours or so.
Additional FeaturesRemote Radio Controlled cut off, just in case!
Still working on the automatic wings....

20/12/09 Did a 5 mile round trip today, and still had lots left in the batteries. Temperature was below zero and we had some issues with traction!

10/04/10 Changed to 50 Ah batteries, seems to have more punch, and range its more than required for local trips.
