We're on a mission to develop e-bike powertrain technology which outlasts and outperforms with our combined gearbox and motor mid-drive system.
- We are an innovative start-up company based in Edinburgh, Scotland.
- We are developing a revolutionary ultra-durable e-bike drive unit.
- Our gearbox based system is designed for longevity, ensuring that your ride is never interrupted by a failing drivetrain, making drivetrain maintenance a thing of the past!
We aim to change the way e-bikes are powered, and change the way products are designed and manufactured by embracing a circular economy model. Our drive unit is designed to outlast the rest of the bike, with minimal maintenance. The system has consistent & dependable gear shifting and a powerful electric motor to boost your ride.
How it works
Our sealed gearbox and motor design has several advantages over traditional derailleur gearing:
- Dependability: 20 year design life, very low maintenance.
- Durability: Robust, sealed unit. No cables, no exposed parts.
- Noise: No loose chain rattling.
- Heavy duty: High load capacity.
- Consistent: Gearshift performance at the touch of a button.
- Kinematics: Centralised mass delivers improved handling & suspension performance.
Intra-Drive’s drive unit features an 8 speed gearbox, with a 427% gearing range. Gear change is sequential, using an electric actuator housed inside the gearbox. The hardened steel gears are protected from the elements, inside a sealed, oil lubricated enclosure. Water, grit, and other gear killing materials don’t stand a chance!
Empowering your ride!
We have developed proprietary motor technology, which integrates seamlessly with the 8 speed gearbox, forming a single compact unit.
- Compact, modular, high torque density.
- Innovative reduction gearing arrangement.
- 100+Nm Torque at rear wheel.
Wireless ShiftingThere are no cables connecting the rider interface on the bars and the gearbox. Removing cables that have the risk of being damaged removes another vulnerable part of the e-bike system.
Our control algorithm will constantly monitor torque, cadence, wheel speed, motor temperature, and will interface with the electric motor, user controls, and gear-shift actuator.
This means the system is highly configurable, allowing for a fully managed shifting experience that can optimize the way the bike shifts gear. Automatic shifting could be made possible with this system in the future with a simple software update.
What they are saying about us
Your system is honestly the best e-bike solution I have seen. I never got why e-bikes were clinging onto derailleurs and external gears, it’s like using a microprocessor to do maths on an abacus!
I am very sure that the integration of the engine and gearbox in the bottom bracket area will be the next big step in the evolution of the bicycle industry. Today’s derailleur systems wear very quickly in combination with powerful e-bike drives and therefore a motor and transmission combination is currently the solution everyone is looking for.
