The ultimate stealth e-road bike, with hidden electric power assistance at the touch of a button and when you need it most. With its long-range and market-leading weight you can climb faster and ride further, whilst experiencing less fatigue than you ever dreamed possible. Sharing the same DNA as the high-performance Endurance SL series results in a bike that gives you a significant performance boost to get you over previously unimagined mountain passes, keep up on hilly group rides and smash that ride that took you outside your comfort zone. Make it possible with the Endurance SL e.

E-Road Bike of the Year Winner

Fully internal cable routing and compatibility with the Level 5 carbon integrated handlebar system for a super-clean, cable free, front end and a drag reduction of up to 40% when compared to a traditional handlebar and stem.


The lightweight MAHLE ebikemotion 36V/250W hub-drive motor system provides 3 smooth levels of power assistance up to a maximum of 15mph, with zero drag in off-mode. Ensuring your ride feels as natural as a modern high-end carbon road bike.


To preserve the high-performance carbon road bike looks it was necessary to secure a slimline and lightweight Panasonic 250W battery that would fit discreetly within the downtube. A battery that would reach full charge in only 3.5 hours from fully depleted and is capable of providing on average of between 60-80 miles of assistance over variable terrain. Ensuring that there is plenty of power on hand for even the longest of road rides.


An advanced Toray T800/T1000 monocoque construction and full EPS inner core system for consistent strength and improved torsional stiffness. The aero efficient tube profiles provide 28.5% less drag than traditionally shaped framesets. Designed with dropped seatstays for additional comfort and improved power transfer.


An easy to use, top-tube mounted, control button enables the power assistance level to be selected whilst on the move, as well as indicating the amount of battery charge remaining.

I am so enjoying quiet London in lockdown on my new Endurance SLe 105. It’s nearly 40 years since I visited Regents Park On a bike. The quiet E motor is a godsend and I can keep up on hills especially with my partner on his Colnago.
Thankyou Ribble for making this 61 year old lady a happy bunny.
5 stars all the way

The whole experience of buying a new bike from Ribble was easy and efficient. The bike build process allowed me to create the very bike that I've always wanted.
Throughout the process, communication with Ribble customer services staff was friendly, attentive and very helpful. I was kept informed of the progress of my bike, through the various painting and equipment build.
On arrival, the bike was easy to complete the assembly of and I was ready to ride within the hour.
I am so impressed with the quality of everything about my bike, it is a dream to ride, light, agile and responsive, my perfect bike. Whilst I'm riding, I can't get the smile off my face.

Frequently Asked
Do I need to pedal to ride this ebike?

Yes, our e-bikes are pedal-assisted models which require rider input at all times.

I’m worried that I won’t have full control over the bike?

There’s no need to worry, being a pedal-assisted model means you are in full control at all times. When a power assist level is selected the motor simply provides a little extra boost whilst you pedal and does not take over.

Do I need tax, insurance or a licence to ride the ebikes?

No, pedal-assisted electric bikes do not require you to hold a valid driver’s licence, pay tax or take out insurance.

How do I charge the battery?

To charge the battery you simply plug the bike into a household socket using the supplied charger and cable. (The optional range extender can also charge the main battery whilst you are on the move).

Can I ride this in the wet?

The bike and propulsion system are fully weatherproof so, can be ridden in all weather conditions.

Can this bike be purchased on a Cycle to Work scheme?

Yes, all ebikes can be purchased through all the major Cycle to Work scheme providers. The government have even abolished the £1000 limit making obtaining an ebike through Cycle to Work more beneficial than ever.

Is it possible to test ride the bike?

Test rides of the e-bike are available from Ribble HQ in Preston. We would advise that you contact us ahead of making your journey to ensure that there is availability for your test ride. Alternatively, you can hire the e-bike from E-Venture Bikes in Keswick, the rental cost will then be deducted from your purchase should you decide to buy one of our e-bikes. We also host various demo days around the UK and the details can be viewed via our social channels or events section of the website.

How much does the Endurance SL e weigh?

Builds start at just 11kgs and this includes the complete motor system which weighs only 3.5kgs.

How much does the Endurance SL e weigh?

Builds start at 11kgs, the Sport build with Shimano Tiagra weighs in at 12.4kgs and the Enthusiast build with Shimano 105, 11.95kgs.

What electronic drive system does the SLe use?

The SLe has been built around the Ebikemotion X35 system.

Can I alter the assistance levels of the motor system?

Yes, you can cycle through 3 different assistance modes (which can be configured further in the app), or choose to have the motor turned off completely; all at the press of a single button.

How does the motor work?

The SL e’s motor system is 'pedal-assist', which means that the motor supports you when you pedal the bike.

How fast can I go on the SL e?

The SL e’s motor system will power you until you reach 15mph, at which point (by law, and as with all e bikes in the UK) the assistance will cut out. If you drop below 15mph the system will automatically kick back in with assistance if required.

What is the range of the SL e?

The range of the SL e depends on a number of factors including rider weight, route profile and temperature. A rider of 90kg, on a varied route including climbs, descents and flats can expect a distance of up to approximately 100kms (62miles).

Can I go faster than 15mph?

Yes, and with builds from only 11kgs you may find yourself above this speed a lot of the time. The motor will only assist you up to 15mph, and for speeds above this you will be relying on your legs.

What if I get a puncture in the rear wheel?

It is simple to disconnect the rear wheel from the frame by unclipping the connector on the chainstay and releasing the nuts on the rear axle. Then reconnect by clipping the cable back in, insert the wheel and tighten the nuts.

What is the warranty on the frame?

The frame has a 3-year warranty against manufacturing defects. All other parts are covered by the manufacturer's standard warranty including the Ebikemotion system.

Can I fit mudguards?

Yes the frame is compatible with full mudguards thanks to its integrated mudguard mounts.

What is the maximum tyre width that the frame can accommodate?

The Endurance SL e is suitable for tyre widths up to 32c without mudguards, though this is dependant upon the model / brand of tyre fitted. With mudguards fitted the bike will accept 25c tyres.

What type of riding is this bike best suited for?

The Endurance geometry of this frame is best suited to comfort and efficiency over longer distances on road, as well as an aid to climbing. If you're going to be riding off-road often, we would suggest the CGR AL e which has the same Ebikemotion system.

How many bottle cage mounts are there?

Each frame size has mountings for 2 bottles.

Does the frame have fittings to allow a rack to be mounted?

No, the frame does not have rack mounts incorporated. For an e-bike with rack mounts, see the Hybrid AL e.

Is it Di2 compatible?

Yes, thanks to its fully internal cable routing the frame is fully compatible with electronic groupsets.

How long does it take to charge the battery?

From flat the battery takes 3.5 hours to reach full charge.

Do I need to remove the battery to charge?

No, the charging port is accessible easily on the outside of the frame.

How will I know how much battery I have left?

The top-tube button indicates battery life at a glance with a simple colour-code. White means you’re at full battery; progressing down through Green, Amber and finally Red to indicate 25% remaining.

Is there an app to use with the system?

Yes, the motor system’s companion app is compatible with both Apple and Android OS’s and offers a full suite of functionality; from monitoring your exact battery life, to pairing the system with a heart rate monitor and having the motor kick in at a specific BPM limit.

How does the SL e’s weight compare to other E-Road bikes?

The SL e is one of the lightest e-Bikes currently available. As reference points, the Pinarello Nytro is 13kgs; and the Orbea Gain is 11.3kgs.

Is the battery and /or motor replaceable?

Yes, the battery is accessible by removing the bottom bracket. The motor is also easy to replace.

Are the brakes flat mount or post mount?

The brakes are the most current flat mount variant.

What plug sockets are supplied for international orders?

Our SL e bike is supplied with a 3-pin UK adaptor.

Will the battery be chargeable in the USA as a different voltage is required? (also applied to other countries)

Yes, bikes shipped to the US are equipped with a drive system that offers a higher maximum speed and includes a US plug. Though charge times may vary to those stated for the UK.

How do you charge the battery?

You charge the system via the charging port that is easily accessible on the top of the bottom bracket shell.

What is the life expectancy of the battery?

Battery has a life expectancy of around 500 charging cycles.

What BB does it take?

The Endurance SL e takes a press-fit style of BB, Shimano builds require a 86.5x41 BB and Sram a BB86.

Where does the additional battery mount/plug in?

The additional battery comes in the form of a bottle and is supplied with it's own bottle cage.This replaces the seat tube mounted bottle cage (this cannot be mounted on the down tube), the charger then plugs into the charging port on top of the bottom bracket shell.

Is the bike supplied with pedals?

Due to the many different systems people use we do not supply pedals with bikes but you can find a great array of pedals here.
