GAIN D50

Designed from the ground up for gravel, Terra isn't a repurposed road bike or a slimmed down mountain bike. Add comfort to your road adventures, finally discover where that dirt trail leads or let your trips spread overnight. There is a wide world out there and Terra is ready to explore it with you.

THE MANY FACES OF JOY

Rider and bike working in perfect synergy, you are breathing hard and your heart is pumping but you are in control and having fun. Gain brings enough power to turn gravity down a bit but not dominate the ride or remove the satisfaction. The natural assistance blends invisibly into the background, leaving you feeling like you are fitter than ever. This isn’t about riding faster, it isn’t even about riding further, this is just about having more fun each and every time you ride.

THE PHILOSOPHY OF GAIN

Enough Power is a concept which is central to our vision of e-road. A completely integrated system which brings together power, range and interface to deliver a natural ride with nearly silent, unobtrusive assistance.

GAIN IS A BIKE

Natural handling means tuning geometry and rigidity to optimize performance. In this respect, Gain is just like any great road bike. Natural pedaling means silent and unobtrusive assistance at lower speeds and no added friction, leaving you free to pedal as normal at higher speeds.

THE FUN IS ENDLESS

The biggest battery on the market, combined with our 1.5 factor, gives more range that ever. Which is useful because you will be having so much fun, thanks to GAIN’s intuitive handling and natural pedalling that you might well just forget to stop.

ENOUGH POWER

The Enough Power concept is central to our vision of e-road. Tuning the motor's power delivery allows us to increase the range while giving a more natural ride. The subtle, integrated controls and display, coupled with the nearly silent assistance, remove distractions, leaving you free to enjoy the ride.

GAIN CARBON
THE X20 MOTOR

The Mahle X20 motor is the lightest, most compact e-bike drive system on the market, making it the obvious choice for GAIN. 55Nm of nearly silent, frictionless assistance gives more than enough power for even the toughest climbs, all with a total system weight of 3,2kg, including the 350Wh battery.

GAIN ALUMINIUM
THE X35+ MOTOR

The Mahle X35+ motor offers up to 40Nm of nearly silent, frictionless assistance. The sophisticated transmission system provides smooth, balanced, and reliable pedaling assistance to improve your rides without making them too easy.
Note: Assistance is limited to 25kmph in EU / UK and 20mph in USA / Canada in accordance with local regulations.

TUNED MOTORS

Working with Mahle to develop our Enough Power tune was key to making Gain. Peak torque is applied smoothly, mirroring your input and feeling natural and unobtrusive.

A BETTER BATTERY

The battery is one of the most noticeable components of an eBike system, so every step has been taken to find the lightest, smallest, and most discreet unit. The beauty of our Secure Battery System is that it allows us to fit more battery in a smaller space.

PURE ROAD GEOMETRY

One of the most important points to consider when determining geometry is that the bike must be easy to ride, meaning you have precise control over the bike.

AUTOMATIC MOTOR CONNECTION

With Gain Carbon, removing and refitting your rear wheel has never been so easy. There are no more fiddly connections for the motor; instead the motor automatically connects when you insert the wheel.

ICR PLUS

Cables are carefully guided along the best path under the stem and through the head tube, with no rub or rattle, and are optimized for both traditional and electronic shifting systems.

INTEGRATED LIGHTING

Fully integrated lighting is just one more feature to enhance your ride. Gain is safer and more functional with head and tail lamps that announce your presence day and night. The built-in light sensor automatically switches GAIN´s inbuilt lights on and off.

LIGHTEST IN CLASS

No other e-road bike with this battery capacity offers lighter weight. GAIN takes that one step further with the Enough Power concept meaning that when it comes to range, there are no bikes that come close.

OMR CARBON | HYDROFORMED ALUMINIUM

OMR frames add high modulus and high strength fibers to a standard layup to improve stiffness-to-weight ratios.
Using aluminum technologies as advanced as our carbon manufacturing ensures our aluminum bikes are never second-best.

DYNAMIC STRUCTURE

The frame's lower spine handles the majority of torsional and lateral loads. There is no doubt about it; resistance to flex here translates directly to more watts to the wheel and a sensation that power transfer is instantaneous. So why do many e-road bikes compromise this area?

GAIN CARBON

E-Shifters
The practicality and simplicity of the system doesn’t finish there; we have included the new e-Shifters, so you can safely set the assistance level without moving your hands.

Pulsar ONE screen
The Pulsar ONE screen shows detailed system and route data for riders who want more information. Or you can quickly remove it and focus on enjoying the ride.

GAIN ALUMINIUM

IWOC ONE Display
With the simple iWoc ONE interface you can power the system on or off, check motor assist level and view the remaining battery charge. Colored LED lighting puts all the information you need right at your fingertips.

PAS Sensor
Gain H’s smooth and balanced assist requires an advanced sensor. The discrete PAS sensor integrates almost invisibly with the cassette and seamlessly adjusts the power output according to your pedaling input.
