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
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
