We recommend the Ecarpat Arena for children who want a bike that rolls over sand, snow and loose gravel. Hycline lists 20×4.0 inch fat tires, a high-carbon steel frame, a suspension fork, Shimano 7-speed gearing with a grip shifter and front and rear mechanical disc brakes for riders about 4 to 5 feet tall, ages 6 and up.
Where it fits.
What stands out
- Wide 20×4.0 inch fat tires with a shock-absorbing design for comfort.
- Shimano 7-speed gearing with a grip shifter.
- Front and rear mechanical disc brakes.
- A suspension fork and high-carbon steel frame.
Before you buy
- Fat tires add weight and rolling resistance on pavement.
- Sized for riders about 4'0" to 5'2", so older teens will outgrow it.
- The listing gives no weight for the bike itself.

Who it suits
The Arena is for children aged six and up who ride in sand, snow, gravel or mixed terrain and want a stable, cushioned bike.
Fat tires and fork
Four inch tires spread the load and soak up bumps, and a suspension fork takes the sting out of hits to the hands.
Gears and brakes
A Shimano 7-speed drivetrain with a grip shifter gives easy changes, and mechanical discs at both wheels give immediate stopping.
Our buying advice
Choose it for adventurous riding. For mostly paved routes, a lighter standard-tire bike is easier to push.
