Frequently Asked Questions

Not at all! In fact, we designed the assembly process to be the perfect weekend father-son project. It comes 85% pre-assembled. All you need are basic hand tools and about 1 to 2 hours. It’s a great opportunity to turn screen time into "wrench time" and teach your teen the basics of bike mechanics.

We built the FLASH to grow with your child. The standard setup is perfect for riders aged 13+ (around 4.5 FT to 5.8 FT). As they grow, our high-clearance frame allows you to upgrade to larger wheel sets (adding up to 2 inches / 5cm of height). Plus, with a max load capacity of 265 lbs, even Dad can take it for a spin!

"Mode 4" is powered by our smart, OTA-upgradable controller. We know teens want to do cool stunts, so we engineered a safe way to learn. Mode 4 acts as an intelligent assist, managing the power delivery to help them pop a "dummy-proof" wheelie while preventing the bike from flipping over backward. It delivers pro-level thrills with built-in parental peace of mind.

Yes! We know riders love to make their bikes their own. The bike can be modified, and we will soon be releasing official mod parts, including larger rims and other custom accessories to level up your ride.

This bike packs a punch. It features a top speed of 35 mph and delivers an impressive 180 Nm of torque for quick acceleration and hill-climbing power.
