Background
CyberQuad is the second Hacky built by Alex, the first being Trikemare. Trikemare was a reverse trike that was unstable during cornering. Cyberquad was built with the aim of being a much more stable Hacky with the aim to also be able to fit in the boot of a hatchback car without being disassembled. The Hacky as built in 2021, first competing at the Fully Charged Live event of the same year.
The theme is loosely based on a cyberpunk look though was never fully realised before becoming inactive in 2024. Despite the name there is no relation to the announced Tesla CyberQuad.
Construction
Intended to be a quick build to produce a stop-gap racer between Trikemare and an eventual more competitive one a children's 50cc quad bike was chosen as a base. This was chosen as it would result in a very low BOM cost for the majority of the components and an already completed front end with steering and suspension. Due to this Cyberquad shares many common components with low cost mini-quad and mini-moto machines giving ready acces to cheap spare parts.
The chassis was stripped of the petrol engine and top (seat) supports. The lower frame was then strengthened and extended with the rear frame being built utilising elements of the original rear frame. CyberQuad is nearly all steel and HDPE in construction.
The steering on a children's quad is mechanically limited by the steering arms hitting their mounting, in order to be able to corner more aggressively the steering axle mounts were extended to allow a higher steering angle. While still using the original parts the steering arms are a weak point and any impacts can result in them twisting.
CyberQuad runs a single motor with a single stage reduction using T8F chain to a solid rear axle, understeer is reduced by lifting the inside rear wheel during cornering. The front suspension noticeably helps cornering and runs softer springs than is typically found on even a childrens quad. The rear wheels often had to be run over-pressure as the demand on them was far greater in CyberQuad than their intended use as a childrens quad leading to them occasionally bursting during races. These were replaced with Go-Kart Wheels to resolve the problem. A single brake is used on the rear axle after the original front brakes were removed as they were not found to be effective.
Cyberquad is notable in being one of the smallest racers during it's time on the track measuring approximately 130cm Length and 60cm Width with a weight of ~35kg.

Powertrain
CyberQuad utilises a MY1020 2000W brushless scooter motor (Similar to the common VEVOR motors though predating them). Transmission is through a single stage T8F reduction onto the stock mini-quad rear axle, geared for speed is approximately 22MPH.
The ESC is a generic unbranded 2000W E-Bike ESC running on 12S LiPo 12Ah (2x 6S packs in series).
During racing the power usage typically peaks at 36A.
