There are practically no limits on Jena Hybrid’s usability and to the available configurations. The clearance between frame / fork and wheels allows you to install generously sized tires on 28” wheels or 650B MTB wheels. With 28” wheels you can install tires up to 44 mm wide, whereas with 650B MTB wheels, you can install 48 mm wide tires, equivalent to 1.95” (tested on Vittoria tires). There are numerous available supports that allow the installation of bottle holders, bags, carriers and mudguards. On the front fork, for example, you can install two bottle holders or one lowrider carrier for bags.
JENA HYBRID
FREE TO CHOOSE
Jena Hybrid has a carbon monocoque frame and fork. The frame’s geometry is similar to the Jena, offering a performance endurance ride combined with a comfortable ride position for long hours spent in the saddle.
The Jena Hybrid features traditional components like hydraulic disc brakes, 11 speed transmission and carbon or aluminium rims. The only component added to the traditional configuration is the rear hub containing the 40 Nm Ebikemotion motor to assist pedalling.
The motor is powered by a 250 Wh battery perfectly integrated inside the frame’s down tube. System control (on, off and monitoring) is controlled by the iWoc button installed on the handlebar, allowing the rider to choose Jena Hybrid's various assistance modes.

USABILITY

THE FEEL OF A NORMAL GRAVEL BIKE
The motor is positioned inside the hub of the rear wheel so the lower bracket can be sized like that of a regular bicycle. This lets you install standard chainsets. This solution maintains the pedalling sensation of a traditional bicycle.

IMPROVED RIDING SAFETY
We improved riding safety by installing the iWoc button on the handlebar. The button is installed with a support on the handlebar, so riders can interact with the Ebikemotion system while keeping their hands firmly on the handlebar. On the Jena Hybrid, riders can select the assistance level and check the battery charge while keeping both hands on the top of the handlebar for safe off-road riding.
GERMAN EXCELLENCE
Our Ebikemotion division has partnered with automotive technology supply leader Mahle to develop and manufacture some of the lightest and best integrated pedal assist systems on the market.
JUST LIKE RIDING A REGULAR BIKE
The X35+ PAS includes a series of components that integrate seamlessly into the latest racing bikes. Weighing just 3.5 kg overall (motor, battery, cables and controller), it’s one of the lightest PAS on the market. Our X35+ version uses the ANT+ communication protocol to connect to the most advanced cyclocomputers on the market.
MOTOR IN REAR HUB
The drive motor is installed in the rear wheel hub, engaging assistance fluidly and silently. When you stop pedalling, or your speed exceeds 25 km/h, power output stops with no sensation of braking friction.
GENTLE POWER
40 Nm torque is perfect for road or light gravel use. This well-balanced power helps better manage battery life on faster and more competitive routes. The sensation when assistance engages is similar to when someone gives the bike a push on a hill or in a standing start.
250 Wh BATTERY CAPACITY
Modest capacity perfect for lightweight pedal-assist bikes like our Hybrid series. The battery is small for easy containment inside the down tube. The system's total capacity gives you peace of mind for outings with major altitude differences.
INCREASE YOUR DISTANCE
Extra battery life expands your pedalling horizons. Battery capacity increases power delivery time by about 80%. The additional battery can be attached to the seat tube using the rivets for the second water bottle holder.
RECORD-BREAKING WEIGHT
The lightest PAS on the market. The miniaturised components plus a hearty dose of technical characteristics provide record weight performance.
ANT+ CONNECTIVITY
The system uses ANT+ to dialogue with third-party devices. This provides all kinds of additional information that can be displayed on the latest cyclocomputers, such as Garmin and Polar.
EFFECTIVE PUSH
The truly lightweight motor’s maximal 250 W of power boosts pedalling effectiveness. The motor engages following the power delivery curve based on how you use the bike. Cadence triggers fluid and effective power with no feeling of resistance.

The most frequently asked questions
The maximum speed attainable with the motor engaged is 25 km/h.
The pedal assist system weighs 3.7 kg with the battery and electric motor. It is the lightest system currently available on the market.
There are three diferent assistance levels, which can be adjusted to your needs in the eBikemotion app (once the app has been paired to the bike, go to Settings > Motor Settings).
Guaranteed autonomy varies depending upon a number of factors: driving style, assistance level, the user’s weight, the slope of the route and pedalling ability. Testing shows the possibility of covering an uphill distance of between 1000 m and 2000 m depending on the difficulty of the route. With a full battery charge, you can ride uphill for more than an hour and a half.
We do not recommend removing the battery. However, the Jena Hybrid can also be used in off mode.
Yes, by installing an optional second battery placed inside a "dummy bottle" on the seat tube of the Jena Hybrid. The total capacity is 460 W/h.
No, Jena Hybrid’s lithium battery can be charged at any time, because it does not have a memory effect.
The guaranteed number of recharges is 500 times. After that, recharges will decrease to approximately 60% of the initial capacity. Over 500 recharges, battery capacity will gradually decrease.
Yes, you can check the battery charge level via the iWoc indicator light on the top tube. The key to the light colour is provided in the Jena Hybrid leaflet. If you want to know the precise value of the battery charge, connect to the Ebikemotion app.
If the bike is not going to be used for a long period, we recommend you charge the battery at least up to 60% before leaving it unused. If after six months, the charge level is less than 20%, we recommend charging it again up to at least 60%.
Of course. The system is waterproof.
You clean Jena Hybrid like any other racing bike. The bicycle must not be washed with high pressure water, as water could get into the motor or communication port above the bottom bracket box. We recommend wiping it with a soft cloth and mild soap, then drying it completely before use.
The electrical system requires no special maintenance. To maintain maximum pedalling efficiency over time, Wilier Triestina strongly recommends regular maintenance and inspections every 12 months at an official Wilier Triestina dealer.
The backlit controller on the crossbar will flash pink. At the same time, the Ebikemotion app will display a red failure / fault warning triangle.
Yes, the Ebikemotion app has a basic diagnostic function. Your authorised Wilier Triestina dealer has more advanced diagnostic tools.
If your bike should have a failure or fault, you can first consult the Ebikemotion app diagnostic/troubleshooting tool. If the problem persists, you will need to contact an official Wilier Triestina dealer to check the problem using advanced diagnostic tools. Any personal action different from those specified in the troubleshooting guide will void the product warranty.
Contact the Wilier Triestina dealer where you purchased your bicycle or via the contact form at https://www.wilier.com/en/contacts
A printed getting started guide is provided with the Jena Hybrid at the time of sale.
Yes, you can replace the cassette with one of the same size. Ensure you reinstall the original closure ring in the same position or the system will not function.
