Project Chenga: ‘A new school Street Bike with old school vibes’

The brief was to design a brand-new street bike from the ground up using the latest technology and components available on the market. The bike had to fulfil the demands of the rapidly emerging wheelie scene, but also be tough and versatile enough to cater for how the wheelie culture might develop (as tricks progress and crossover to BMX/trials/street riding). Looking to the future, we set to work creating a true BMX/MTB/Cruiser/Retro hybrid.

With a massive input from our key OG wheelie riders and ultimate design realisation from our highly experienced product design team, the result is in our minds and of the opinions of many influential riders in the scene, a ‘masterpiece’. The first totally dedicated wheelie/street bike that brings all flavours together and ticks all the boxes for all riders. Wheelie it, Jump it, Trick it, Race it, Chenga is ready. We just set the record straight, now its time for the rest to follow.

For the latest release of Chenga, we went back to the drawing board to take this ultimate wheelie machine to the next level. With revised tubing and geometry, we have added strength to all the right places, giving you the most comfortable ride yet. For those pushing the “frame work” boundaries, the Chenga now features outboard disc mount to allow for extra room. The new models are finished off with our latest tyre, the Snakeskin version 2 – constructed from an all new compound and deeper knurls, making it them the best wheelie tyres available.

    How to claim

    Warranty claims will only be handled via email ( If you do not supply all of the requested information, your claim may be rejected.

    Completes & parts

    6 months manufacturer’s warranty covers unexpected failure/defect of all parts/components that may not be attributed to fair wear and tear, or crash damage outside that considered normal use. The claimant must be the original owner/purchaser and produce a receipt to prove the date of purchase. The parts/components must be free from modification including shot blasting and/or painting/powder coating where this may be attributed to the failure.

    Important - 1 week service

    As your bike will have been sent to you via mail order it will be part-assembled (handlebars, seat, front wheels, pedals and other components will need to be assembled) it is your responsibility to ensure it has been assembled correctly. We allow you to assemble by yourself. However you must get a 1 week service by a qualified bicycle shop technician in order to qualify for your warranty. This is to ensure you have assembled your bicycle correctly and that everything is adjusted correctly e.g. spokes will need tightening, maybe your chain is too loose, brakes not set correctly, tyre pressure incorrect etc. If you do not have your 1 week service record (signed and stamped receipt), then your warranty is invalid.

    Examples of items not covered by your warranty:

    • buckled wheels• worn tyres• worn/broken chains (unless clearly a manufacturing defect)• worn sprockets• worn bearings or hub internals• bent forks / frame / bars / axles / cranks / pedals• worn brake cables

    Examples of items that are covered where it is clear there has been no abuse or misuse (note: you will need to supply photos of both sides of your bike & then may further be asked to return the failed component):• cracked or broken frames• cracked or broken forks• cracked or broken bars• cracked or broken hubs• internal axle failure bb/wheels• visible manufacturing defects to any part or component (should be reported as soon as noticed)If a repair or replacement is not possible Mafiabikes reserve the right to offer an alternative of equal or greater value (colour may vary) or a partial refund proportional to the remaining life of the product.You are expected to keep your bike in serviceable condition. any failure attributed to incorrect or lack of maintenance will be easily detected by our engineers & in most cases rejected.When you make a claim, you will be expected to provide photographic evidence of your complete bike (photos of both sides even if it is a single small component failure) including close up shots of the failed component(s). In most instances you will then be required to send the failed part/component back to our head office for inspection at your own cost.
