Tuttio ARC-I

The ARC-I is Tuttio's kids electric dirt bike: a 36V bike with a 750W brushless motor, a removable 36V 13Ah battery and 16x3.0 inch tires. Its spec sheet notes the speed is limited out of the box for safety and can be unlocked. Most of the people who land on this page are parents, so we keep it practical. The parts below are grouped by the jobs parents most often face.

Tubes and tires come first. A 16x3.0 tube is a common reorder, and low pressure makes pinch flats more likely, so check pressure before rides. Brake pads, brake cables and levers come next, since a dropped bike often bends a lever. After that come the kickstand, pedals, fender and saddle.

If the ARC-I stops working, check the simple things before buying electronics. Is the battery charged and seated? Is the charger's light changing? Are the brake levers fully released, since some kids bikes cut power when a lever is pulled? Then move on to the throttle, display, controller or mainline harness, all listed here. WiredWhips carries parts for many electric dirt bike brands, including youth models like this one.
