When purchasing a mafiabike. You will have chosen an excellent bicycle from a manufacturer that prides itself on the supply of the best quality bikes at the most affordable prices.
Please note, your bicycle has been supplied in a carton (box) in a semi-knock-down state. This means it requires some basic assembly & a thorough inspection by a competent experienced person prior to riding.
We strongly recommend that this inspection is carried out by a trained bicycle technician at a bicycle shop where they regularly build and service bicycles. It’s paramount for the safety of the rider that this bicycle is thoroughly checked over for any potential safety issues prior to riding. We will not accept any liability whatsoever for injury or death sustained as a result of improper assembly and inspection of your new bicycle.
If you should encounter any such issue during assembly/inspection please do not hesitate in contacting us using the appropriate wblog and instagram to arranty or returns form to be found at www.stomp-group.com
For your safety and also to validate your warranty, your new bike needs to be serviced after approximately 1 week of riding or 50 miles (whichever comes sooner). This is because all moving parts are liable to bed-in and require adjustment e.g. crank bearings, wheel bearings & headset bearings. The chain may also require re-tensioning. All nuts & bolts should also be checked to ensure they are sufficiently tight along with wheel spokes (especially on BMX bikes which tend to be ridden much harder than other bikes).
All mafiabikes BMX’s are designed for use at an entry-level. This means small airs, jumps or hops (max 1 foot or 12 inches), which may incorporate basic tricks such as up to 360° spins). Foot jams, foot jam whips, bar spins or manuals. If you push your BMX beyond this level, you do so entirely at your own risk.
Should you wish to go beyond these limits we advise you to upgrade your bicycle to one that is built entirely of aftermarket parts. Servicing (continued) For your safety and for the optimum performance of your bicycle it should be checked thoroughly by a trained bicycle technician on a regular basis. This is especially true for BMX bikes, which may sustain regular immeasurable impacts.
For your safety and for the optimum performance of your bicycle it should be checked thoroughly by a trained bicycle technician on a regular basis. This is especially true for BMX bikes, which may sustain
regular immeasurable impacts.
A bicycle that has not been serviced correctly and is ridden in a manner which it may sustain regular immeasurable and unquantifiable impacts, may cause component failure and potential injury or death. Stomp Racing LTD will not be held liable in any way for any injury or death sustained as a result of improper/incorrect use, servicing or maintenance.
As a guide, we suggest a full inspection by a qualified person every 3 months however this is only a guide & is by no means exhaustible. It is your responsibility to ensure your bicycle is safe to ride at ALL TIMES.
If you ride your bicycle in an ‘extreme way’ i.e. to perform tricks such as. BMX, you should inspect your bicycle EVERY time you ride it and also during the period you are riding it. It is highly recommended that you carry any essential tools you may require for continued maintenance whilst
you are riding.
This is perfectly normal and accepted practice whilst riding BMX. E.g. an impact from a jump or air may cause your bars to move, also your cranks or your spokes could work loose. You should be prepared at all times to be in a position to rectify any servicing or maintenance issue which could potentially cause component failure, injury or death. Your safety is entirely your responsibility.
The majority of Mafiabikes are supplied for off-road use. If you intend to use your bicycle on the road, please ensure you have the appropriate legally required features to do so, such as front & rear brakes, chain guard, reflectors, bell.
If you do not have these items but you want to ride on the road, we can supply them free of charge.
Wherever you ride, you should take every precaution to protect yourself from potential injury. Always wear a protective helmet and gloves and make sure you stay visible to others by wearing brightly coloured clothing such as a reflective jacket.
If you are riding in a skate park or other off-road location, ensure you are always well protected. If performing tricks or riding difficult obstacles such
as ramps, curbs, rails or trails we strongly advise the use of a full-face helmet, protective gloves, elbow & knee pads, shin/ankle pads & protective shoes
The following is a guide for technically competent persons only, it is not a step-by-step ‘how-to’ guide. It is assumed that this guide is to be read by those who already understand the requirements of a bicycle pre-ride safety inspection. This guide may not be exhaustive.
1. Your brake(s) should be set by the factory, however as it beds in it may require adjustment. To adjust your brake pad, first loosen the allen bolt attaching it to the calliper enough that the shoe will move freely.
2. Next pull your brake lever so the pad makes firm flat contact with the wheel rim. Whilst holding the brake lever, adjust & position the pad so that it sits flat on the rim. Make sure the pad is away from the tyre. A rubbing pad on the tyre will cause the tyre sidewall to fail & the tube to blow out BANG. This can cause injury.
3. Once you are fully satisfied with the position of the pad, tighten the pad retaining bolt/nut whilst FIRMLY pulling the brake lever and preventing the pad from spinning (sometimes this requires 3 hands). This will give a nice flat pad adjustment & very effective braking performance. However, it may also cause the brake to squeal, especially if rim-protecting soft pads are being used (clear pads). To prevent brake squeal, attempt to angle the leading edge of the pad slightly into the rim. The rear of the pad should be approx 1-2 mm off the rim when the leading edge 1st touches the rim. Braking performance will still be good & hopefully, the SQUEAL is reduced or totally eliminated.
Note: if your brakes are not installed but supplied as a kit, please see the separate brake assembly instructions and online ‘how to’ install brake video.
1, The U or V-brake utilises 2 separate levers to apply pressure to the wheel rims. Each lever has a spring which is adjustable in tension. In order for both levers to pull together & for the pads to make contact at the same time, the springs need to be adjusted for balanced movement. If one arm is moving more than the other, you must reduce it’s spring tension (usually as small allen key bolt in the side of the brake/pad lever)
2. Depending on the brake this can be either clockwise, or anticlockwise, therefore you will need to experiment. You are trying to achieve the brake levers to be in roughly the same position at rest & pull together at the same time when you pull the brake. A perfect set-up will see both pads hit the rim at the same time.
Once your brake is set up correctly you may want to finally adjust the brake lever pull for your personal preference. There are normally 2 adjusters, 1 on the lever & 1 on the cable termination on the frame.
Your cranks may come loose from time to time, if they do, this is how to tighten them:
1. Loosen the 2 pinch bolts (where fitted e.g mafia clip), next tighten the centre crank arm bolt (in line with crank axle) then re-tighten the pinch bolts.
2. If your cranks are still after tightening, it may be that you bearings are not fully pressed in. To ensure they are pressed in firmly, remove the crank arms fully & using a suitably sized large socket matching the outer race of the bearing unit, drift the bearing hard into place in the BB housing (using a hammer). Do this on both sides & then re-assemble the crank arms
Tyre pressure is a personal preference. Some people like their tyres soft, others like them rock hard. Your tyres are only designed for pressures up to 60 psi, so always use a pressure gauge & never overdo the pressure. If you desire higher pressure we suggest you invest in some hi-pressure aftermarket tyres.
Your chain should be tight at all times. The reason for this is that a tight chain will make it easier for you to keep your pedals in the desired position whilst performing tricks where your feet leave the pedals e.g. foot-jam whip.
Note: if this is all too complicated & you are not
interested in tight crank arms for tricks, simply align
your rear wheel centrally pulling back on the wheel
till the chain is tight, then tighten the wheel nuts.

Warranty claims will only be handled through the appropriate channel which is our online form. If you do not supply all of the requested information, your claim may be rejected. Please go to the following
page & fill out the warranty enquiry form in full http://www.stomp-group.com/warranty-enquiry-form/
1-year manufacturers warranty. Covers unexpected failure/defect of all parts/components that may not be attributed to fair wear & tear or crash damage outside that considered normal use. The claimant must be the original owner/purchaser to produce a receipt to prove the date of purchase. The bicycle/parts/components must be free from modification including shot blasting non-standard parts and or painting/powder coating.
Please note, you automatically qualify for a 6 months statutory warranty, to extend to the full 1 year you must fill out the warranty registration form which can be found with your purchase or if not you can download a copy from our website www.mafiabikes.com
As your bike will have been sent to you via mail order, it is your responsibility to ensure it has been assembled correctly. If you do not have your 1-week service record (signed & stamped receipt), then your warranty is invalid. Please note: ‘Raw’ finished frames forks etc will be subject to corrosion at a faster rate than painted bikes.
This is simply because there is no rust protection applied to give the parts the ‘raw look’ i.e. where you can see the blueing of the tubes as a result of welding. Therefore, we cannot offer a warranty on the basis of corrosion. It is advised to minimise the potential for corrosion, that the bikes/parts are kept away from water and stored inside.
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
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
• Cracked or broken cranks
• Visible manufacturing defects to any part or component (should be reported as soon as noticed)
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.
