Background

Theme is to look like Lego blocks. It uses baking trays sprayed in various bright coloured car paints

It takes the 2022 Hacky Racer, Jeepney, and re-themes and improves on that basic design

Construction

How is the chassis constructed?

Majority of the chassis is constructed from 20mm x 20mm box section. Its fully welded together

The box section used allows a level of flex over rough surfaces that is beneficial

Steering? Geometry?

Steering is direct in the style of a go-kart Its has a lot of negative camber, probably too much!


Where are your wheels, tyres, hubs, axles from?

Majority of components are from mini ATVs

There are 2 sizes of wheel/tyre available depending on conditions. 13x5.00-6 145x70-6

How do your brakes work?

Single brake disc on the rear axle with a hydraulic braking system using components from an ATV The master brake cylinder is actuated directly from the brake pedal

Brake Disc
Battery box

Powertrain

Motor Uses a single Vevor 2000W motor mounted to allow the chain tension to be adjusted

ESC Whitebox 1500W e-bike controller that may/may not of had the shunt modified to allow more current

Details of chain and gear ratio? 11:74 sprockets through a chain

Do you have a diff? No diff fitted, a single solid axle

Where is your battery from? Hobbyking but now consistently out of stock

Other Features

Changing the wheel/tyre changes the ratio of the gearing by a few percent which can be handy
