The DreamRide Propulsion System
DreamRide is a breakthrough in e-bike propulsion technology.
The key differentiator: a pedal-by-wire drivetrain, rather than a traditional mechanical chain drive with physical gears.
It allows for virtually limitless customization to the rider experience: pedaling resistance and cadence, acceleration profiles, various ride modes and transmission styles.
The possibilities of a software-defined ride are endless. Core ride modes are ready to go out of the box, and we’re just getting started.
How DreamRide Works
At its core, DreamRide is a seamless integration of a series hybrid drive unit and intelligent software.
The key difference is that there is no direct, mechanical connection between your pedaling and the physical movement of the bike.
Energy Conversion: Your pedaling input is converted into electricity by rotating the generator motor, similar to how a dynamo works.
Energy Storage: That electricity returns energy to the battery, much like those old crank flashlights, but supercharged.
Intelligent Output: ALSO software outputs this energy combined with a charged battery to the 750W traction motor, which sends that power to the rear wheel through a Gates carbon fiber belt, sending the TM-B off the line with the same torque as a car.
This output is managed based on how you like to ride your TM-B. Set your cadence, assist level, and ride mode, and the TM-B responds accordingly.
How fast is TM-B?
DreamRide is capable of outputting 180Nm of torque on TM-B.
That’s fast… like really fast. 0.3 G’s fast, which is about the acceleration of the average passenger car at hard launch. That torque is useful for off-the-line acceleration, which can keep you safe when sharing the road with cars. Most other e-bikes on the market top out at 100Nm.
It is a Class 3 e-bike, meaning it has a top speed of 28mph, a throttle-only speed of 20mph, and a 750W motor. The difference is how quickly TM-B can reach that top speed.
Assist levels
The TM-B has multiple levels of assist to augment your pedaling. At assist level 1, it feels much like riding a normal bike. Assist level 2 can be compared to an output of two of you, doubling your input. At assist level 10, it feels like unlocking 10 you-power.
Battery Configuration | Assist Level Provided |
|---|---|
TM-B Base | Provides up to 5x your pedal input in assist. |
TM-B Performance & Launch Edition | Provides up to 10x your pedal input in assist. |
Hill Flattening
With that much motor power, tackling hills feels like riding on flat ground. TM-B automatically adjusts the motor output to match the incline of the surface you’re on and the resistance you’re up against to maintain a smooth and even ride.
We call it Hill Flattening, and it works on a 30% grade. Whether you’re in Pittsburgh, San Francisco, Los Angeles, or any other place where the hills get ridiculously steep, TM-B will tackle it without breaking a sweat.
Regenerative Braking
Recharges the battery while slowing down, to enable longer rides and less wasted energy.
