Royalbaby
RoyalBaby Front Fender for 20" Bicycle
Front fender only — order a rear separately if you want full coverage. Sized for 20" kids bikes; confirm rim brake and tire clearance before install.
Syncros
Syncros Trail Fender
Universal MTB front fender - zip-ties to the fork crown and lower legs of any suspension fork. Designed to be wide enough to clear a 2.6" tire and short enough not to interfere with crown-mounted accessories. Bolt-on, no tools needed.
Syncros
Syncros Trail 34SC Fender
Fork-specific fender designed for the Fox 34 SC (Step-Cast) and other 34 mm-stanchion XC/trail forks. Bolts directly to the brake-arch holes instead of using zip ties - cleaner install and steadier under hits. Won't fit 32 mm or 36 mm forks.
Syncros
Syncros Trail Fender Squad
Shorter and lighter than the standard Trail Fender - keeps mud out of the goggles without the extra polypropylene tail. Universal zip-tie mount fits any suspension fork. Orange colorway is the only one consistently in stock on Amazon.

What matters for 10 year olds
Ten-year-olds are often at the upper end of kids bike sizing. Most children this age ride a 24" bike, but taller 10-year-olds (over 140 cm) may be ready to step up to a 26" wheel bike or even an XS adult bike. This is where the decision gets nuanced: a well-fitting kids 24" is usually better than a too-large adult XS. Look for proper standover clearance, comfortable reach, and a saddle position that allows the balls of the feet to touch the ground. Gears are standard at this age - a 1x8 or 1x9 drivetrain handles all terrain. Disc brakes are strongly recommended. At 10, children can also start to express preferences about riding style: trail riding, road cycling, BMX, or casual cruising. Let their interest guide the bike type.
Fenders & Mudguards sizing guidance
Fenders are sized to two dimensions: wheel diameter (12-20" for kids, 26"/27.5"/29"/700c for adults) and tire width (commonly 23-32 mm for road, 32-45 mm for commuter/gravel, 2.0-2.4" for MTB and kids bikes). Fenders should sit roughly 8-12 mm clear of the tire on each side and overlap the tire by 5-10 mm. Three broad styles: full-wrap fenders bolt to frame and fork eyelets and cover roughly 60% of the wheel for maximum spray protection (best for daily commuters and rain bikes); clip-on / strap-on fenders use rubber straps or P-clips around the seatpost and fork legs and trade coverage for tool-free install (best for road bikes without eyelets); and minimal racing-style ass-savers protect only the rider's backside and are mostly a token gesture for unexpected showers. Kids fenders tend to be plastic, sized 12/14/16/18/20", and clip to the frame with the bike's existing brake-mount or kickstand bolts.
Most 10 year olds choosing fenders & mudguards also compare gloves for 10 year olds, helmets for 10 year olds, and kickstands for 10 year olds.
Expert tips
- If your 10-year-old is between 138 and 143 cm, this is the sweet spot for a 26" kids bike - it will last 2-3 years
- Consider your child's riding interests when choosing: trail, road, BMX, and casual riding all have different ideal bikes
- A quality 24" kids bike with good components outperforms a cheap adult 26" bike in every way
- This is a great age to start longer family rides - 10-year-olds on properly-sized bikes can handle 15-25 km rides
