Background

East Essex Hackspace built Velociracer to compete in the EMF2024 hackyracer races, using an old broken jeep toy which was subsequently reinforced. The original jeep was badly sun damaged, the plastics mostly broken and the electrics very rusty. When covered in grey primer, we realised it looked a little like Jeep 18 from the Jurrasic Park series, so we reinforced that with red styling and stickers.

The 12v 4x4 drivers were removed and replaced by a single 1800w motor and a go cart axle which was turned on the lathe to accept a mobility scooter diff as it wasn't going round corners.

The battery was built from individual cells, donated by one of the hackspace users who builds motorbikes to beat the electric motorbike land speed records as these were no longer allowed to be used.

Velociracer has twin brakes.

Build Team

Andy Pugh Nick Reynolds Tim Neobard (though all his work was cut out as his welding was awful)
