How to choose
- Rider height and leg length: a bigger wheel needs a taller rider. Ask us about fit.
- Where you ride: gears help on hills and in traffic. Single-speed builds are simpler to maintain.
- Maintenance: big-wheel bikes still get flats, chain wear and brake pad wear. See our BMX repair page.

Basic maintenance that saves money
- Check tire pressure before rides. Low pressure causes big-wheel BMX flats.
- Look for goatheads and thorns after rides near desert edges.
- Keep the chain clean and lightly lubricated. A worn chain costs $25 to repair at our shop, and ignoring it can wear other parts.
- Check brake pads often. Replacing pads is $50 per wheel at our shop with pads included.
- Tighten loose bolts before they cause damage.
When your Mafia arrives
- Look the box and bike over before you sign, and take photos if anything is damaged.
- Ask us before delivery how the bike ships and what assembly or setup is needed.
- Check the tires, brakes, bolts and wheels before the first ride.
- Charge the battery fully using the supplied charger before you ride.
- Contact us if anything looks wrong. Do not ride a bike you are unsure about.

FAQ
Are you an authorized Mafia Bikes dealer?
Yes.
Do you ship Mafia bikes?
Yes. We ship nationwide.
How much is a BMX flat repair?
$40, with the tube and labor included.
Can a beginner learn wheelies on a Mafia?
Many riders do. Wear a helmet and pads, start in an open, flat, empty space, and take it slowly.
Do bigger wheels get more flats?
They can. A larger tire has a larger area exposed to thorns and debris, so check pressure and inspect tires often.
