About Us

At Intradrive, we build e-bike tech for those who crave adventure, because we do too.

We're a team of mountain bikers, hikers, climbers, and surfers who spend their free time on the trails, in the hills, chasing the next adventure.

Founded by engineers with a passion for all things bike, our team benefits from first-hand experience of racing enduro and downhill, daily cycle commuting, and transporting heavy loads (and a dog!) by cargo bike.

We understand the needs of cyclists and share their frustrations with fragile, unreliable, and unrepairable technology.

Meet The Team.

At Intradrive, we're transforming the future of e-bikes with durable, repairable powertrain technology. Fragile derailleur drivetrains and unrepairable motors have limited product lifespans for too long. Riders demand better, and we deliver.

With production tooling complete and our first production run in Q4 2026, we're partnering with leading bike brands to redefine e-bike technology for the long haul.
