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 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 LEVEL5 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 X35+ hub-drive motor system provides 3 smooth levels of power assistance up to a maximum of 15mph, with near-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 maximum capacity when fully depleted in just 3.5 hours and is capable of providing on average up to 60 miles of assistance over variable terrain.


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 ordered my Endurance SLe on the bike builder , this part was easy , the payment was easy and I more than happy with the ordering process and the way things looked. My order went on the 26th Nov 2020 and the promise Date was the 13th Jan 2021. This was where things started to get frustrating. I had an email to say that the promise date had been put back to the 3rd March and this lead to me getting in contact using the online chat . The chat if I'm honest just led to more frustration as I felt I was being fobbed off. Next a phone call to customer services and finally I could talk to someone. I was advised the issue was the group set and it was due to be delivered early Feb, this then got delayed again but the group set was confirmed to have arrived on the 19th Feb and I was told that all the parts for my bike were now in stock but they could not start the build as the frame had not been painted, I was annoyed about this but I was given a build date and was told that the 3rd of march would be the latest. It got to a point again the online chat was getting frustrating , I found that I had to keep contacting them to find out what was happening and on the Phone I put through to Sam Williams an account manager. If I'm honest Sam was brilliant , he listened to me for a start, and when I get wound up I'm not the easiest person to talk to. The issue now was that the rear mech was not in stock, All i know is they had to order a new one and it took over a week. Sam kept calling me to give me updates which was brilliant and in the end Sam arranged for the build and delivery to be fast tracked.
Ok so that was the frustrating bit , My bike arrived on the 17th March , and I have to say its amazing . I assembled the bit that you have to do as it comes out the box , set it all up and checked it over. I was really impressed with the finish and i was so happy that I went through the custom route. I decided to go tubeless and had my new tyres ready , the wheels came with tubeless valves and this was an easy process to do, I wasn't worried about having the extra tyres as I've used them on another bike.
And here's for the Good bit, I took it for a ride tonight . I didn't use the assist at all, rode it like a normal bike . It rode and handled like a dream and I took 5 minutes off a 30mile loop PB , seriously this thing just rolls . My mates are going to be so pissed with me and that's just riding it un assisted. The Di2 is brilliant , the Mavic wheels are fantastic and the level 5 integrated handle bars just look the part and feel so comfortable. I don't think I will use my old bike until the winter now because this does it all. I've not used the assist yet, I've played with the app on my phone but will possibly just add the bike to my Garmin head unit.
Ribble this is one great bike, sorry if i gave you a hard time but you delivered in the end. Thanks you
Julian day
Hi Ribble cycles , I had great pleasure of taking my bike out for the first time yesterday 28th jan . I rode about 20 miles up and down various hills to test the help the e power was giving me , I was pleased with it it will that a bit of time to get used to the assistance that the e motion gives me , it’s a little heavier than I thought it would be but that’s ok ok when you have the assistance on to help up hills

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 any form of road 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 electric components used on our e-bikes are IP54 rated. They are protected against splashing, but not against full immersion. The electric bike should never be subjected to pressurised water from a hose pipe or jet wash, failure to adhere to this may result in damage to the electrical components that comprise the motor system . When transporting the bike on the outside of a vehicle a waterproof cover should be used to ensure the protection of the electronic components from water ingress during transportation.

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 removed the £1000 limit making obtaining an ebike through Cycle to Work more beneficial than ever.

Is it possible to test ride the bike?

Due to the challenges associated with the Covid pandemic, test rides are not currently available. We hoe to be able to offer these soon. 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 hope to be able to reinstate the Ribble roadshows which travel around the UK offering people the opportunity to test ride our bikes. We will update the events page of our website and share the details via our social channels once we have any events confirmed.

How much does the Endurance SL e weigh?

Builds start at sub 10.5kg, the Sport build weighs in at 12.4kgs, Enthusiast - 11.95kgs and Hero - 10.49kg.

What electronic drive system does the SLe use?

The SL e has been built around the MAHLE Ebikemotion X35+ hub drive motor 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 adds assistance to each pedal stroke.

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 battery range of the Endurance 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 using the low power setting can expect an average of 60 miles range. An optional range extender is also available for all of our e-bikes, which takes the total capacity to 456Wh and increases the available range by up to 70%.

Can I go faster than 15mph?

Yes, and with builds available from sub 10.5kg 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 electric bikes?

The frame has a 3-year warranty against manufacturing defects. All other parts are covered by the manufacturer's standard warranty. The Ebikemotion system is covered against manufacturing defects for a period of 2-years.

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 Gravel 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 CGR 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 fully depleted the battery takes 3.5 hours to reach full charge.

Do I need to remove the battery to charge?

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

How will I know how much battery I have left?

The button mounted on the top-tube indicates the remaining battery life at a glance using a simple colour-code. White= 75% capacity or more remaining, Green= 50-75%, Orange= 25-50%, Red= 15-25%, Slow Red Flash= 10-15% and Rapid Red Flash= 10% or less remaining. You can also keep track of the remaining battery life using the Ebikemotion companion app.

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 through the bottom bracket shell and can easily be removed by any MAHLE certified technician. 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 available with UK or US power cables.

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 power cable. 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?

Like any battery, the capacity will start to degrade over time. In the case of the Panasonic battery it should be after approximately 500 charging cycles if its care and maintenance is adequate. Please take some to read ourbattery care blog in which we outline the best practices to ensure that your e-bike's battery continues to function at optimal efficiency throughout its lifespan.

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.
