Marin Hidden Canyon 20″
This Marin is a real mountain bike for your 6 to 8 year old.
The Hidden Canyon moves your child past the training wheels and coaster-brake starter bikes and into a geared bike with hand brakes. If your neighborhood is hilly, it means junior can ride instead of walking up hills. You can go further together than if the little guy or gal were struggling to keep up on a single-speed.
These Marins come with hand brakes (discs even!), a lightweight aluminum fork, chain guards, and 7 gears with a twist-grip style shifter. They are built to the same quality standards as our adult bikes. Most of the parts are made out of aluminum instead of steel, so the bike is rust-resistant and the overall weight is a whole lot less than a typical kids bike.
There’s a quick-release seat post clamp for height adjustments and sealed cartridge bearing headsets and bottom brackets for extra durability (and a lighter weight bike).
By the way, you get quick-release hubs on the wheels so you can easily remove a wheel to fit the bike in the car.
These bikes aren’t disposable junk. When your kid outgrows his or her Marin, these bikes will still be viable, ride-able bikes that can be traded in or passed on to the next child (and the next after that one).
