20" Wheelie Bmx Bike Mafia Bikes

Mafiabikes Medusa 20 Wheelie Bike - Available in multiple colourways   Bikelife/Wheelie culture is blowing-up world-wide but until now, no companies had stepped up to facilitate the smaller riders making their way through the ranks. Medusa 20 now pioneers the featherweight division, hitting hard on the scene and delivering our superior experience and knowledge in a much smaller package. To inspire confidence, our designers foremost considerations were based on weight, geometry and ergonomics. Everything had to be fine tuned to maximise your little one’s game, so they can kill-it no matter what their size. Featuring a 6061 T6 alloy frame with reinforcing gussets and disc brake, the Medusa 20 doesn’t cut corners on quality. Sealed headset, bottom bracket and hubs will keep them rolling the streets effortlessly and the fat 2.4” Lagos tyre and Mafia wheelie seat will provide unparalleled grip and comfort for swerves and combos.

If you do not supply all of the requested information, your claim may be rejected. Please go to stomp-group.com 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 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:

worn tyres

worn/broken chains (unless clearly a manufacturing defect)

worn sprockets

worn bearings or hub internals

bent forks / frame / bars / axles / cranks / pedals

buckled wheels 

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.
