Ebike drive systems offered on our bikes



E-Bikes inspire and drive mobility and are one of the most agile, comfortable and simply clever means of transportation of our time. Cutting edge components and the high degree of design flexibility offered by Bosch E-bike Systems form the foundation for our Motus and Captus models.

The powerful Bosch Drive Unit transforms any pedelec into a clever everyday companion. Wherever you’re heading, an Active Line equipped Raleigh will get you there fast, calm and collected.

The Active Line motor gives just the right level of support with every push of the pedals whether that is for relaxed everyday use or more power for those times when you really need a boost. Its optimized 3-sensor concept performs 1000 highly precise measurements per second, affording optimum power tuning and a unique riding sensation. The Active Line Power Packs ensure the most powerful performance, thanks to their high energy density and long life.

The Intuvia on-board computer serves as the command centre allowing you to switch between four different riding modes; Eco, Tour, Sport & Turbo, as well as displaying information like speed, battery level, distance travelled and approximate range available.

The handy 'walk' button delivers a 'walking speed' power output from the motor for those occasions where you need to push your bicycle up some steps or a short slope. An optimal balance of powered assistance is ensured by three sensors that monitor pedalling power, cadence and speed at a rate of 1000 measurements per second.

Precise motor control and rapid processing of sensor information ensures very low levels of noise and vibration. Reliable, stable chain run prevents chain derailments, and reduces wear. The Bosch system is even clever enough to recognise your gear shifts, and in a split second, reduce power preventing damage to the chain and sprockets.

On the eMTBs offered by Raleigh's sister company, Haibike, Bosch fit the more sporty and torquey Performance CX motors.  These motors are the most dynamic of all ebike motors, offering up to 85nM of toruqe (power at the rear end).  Yopu really can feel the difference when riding on more challenging and technical terrain.  Combined with a 500 watt hour battery the CX drive system gives you a huge range and enough power for a good MTB session..

Bosch is the market leader in E-bike drive system technology - a brand trusted globally for its engineering quality.


Based in Taiwan, TranzX are at the forefront of development, creating smart solutions for E-bikes. Early adopters of E-bike technology, they manufacture their complete system in-house to ensure quality and consistency. Many leading E-bike manufacturers use TranzX systems as they offer reliable performance at an affordable price.

At Raleigh, we use the two newest systems from TranzX; the front wheel F15 motor and mid M16 motor models. Both systems benefit from new communications technology, which ensures that the motor maximises the battery range, and will allow your dealer to set the bike up for you via a USB link.

Handle-mounted power controls are placed cose to the grips, so you can easily select from the three power levels, and use the speed button to give you an extra boost for hills or when you’re late for work!

The F15 motor featured on the Raleigh Spirit and Pioneer models is a powerful, geared front wheel motor. This provides the bikes with great hill climbing assistance, and allows you to quickly pull away at junctions or traffic lights. Adopting the latest gear design allows the motor to be kept relatively small and quiet compared to other front wheel motor systems. The simple LED display indicates the level of power you are using and the remaining battery charge.

For the Raleigh Strada Trail Sport Electric, we use the TranzX M16 motor, as it is ideally suited to the type of riding this bike is designed for. In this instance the motor is directly connected to the cranks providing a smooth and exceptionally efficient transfer of power which is added to your pedal stroke. When combined with the Strada’s 9 speed Shimano Deore gears, the M16 motor gives you the ability to easily climb steep hills on trails and the road, as well as speeding along on the flat. The M16 system features an LCD display that shows your speed, range and the power level you are using. TranzX inspires the modern E-bike experience with intelligent solutions felt in every push of the pedal.


Raleigh has worked with Accell Netherlands, Europe’s largest manufacturer of E-bikes, to develop the E-motion front motor system for the Array models.

This is the best riding front motor system we have ever experienced at this price point. The custom software provides an even delivery of power meaning that the bike pulls away smoothly and without the jerky surge of rival systems.

With 5 power levels plus the boost function on a twist grip you can manage the assistance that the motor gives you to maximise the range of the battery or make the ride as easy as you want it to be. The 300wh battery gives a range of up to 108km on the lowest setting or 22km on high.

This makes it ideally suited to quick commutes and trips around town or rides with the family. The D-light motor is so small and quiet you’ll hardly notice it’s there until you realise how far you’ve gone with so little effort.

Shimano Steps

Shimano are the world’s leading supplier of bicycle components; there are more bikes fitted with Shimano controls than any other brand. Shimano have taken their knowledge of cycling, gained from years of experience, and applied it to produce one of the most innovative E-bike systems available.

The key to the Shimano STEPS system is the integration of the gears, motor and controller to produce a quiet, powerful and efficient riding experience.

For our Shimano STEPS equipped Raleigh E-bikes, we have combined the STEPS motor with Shimano’s Alfine Di2 electronic hub gear, allowing you to change the gear using buttons rather than levers for a fast, smooth and precise shift that doesn’t require readjustment.

This system also gives you the choice to set the bike to automatic shift. Based on bicycle speed and how fast you’re pedalling the Shimano STEPS system will automatically tell the Di2 hub what gear to shift into. So while you pedal, the drive unit brainstorms and, if necessary, temporarily reduces chain tension so the hub can change to the right gear.

In plain English, this means a smoother riding experience because you won’t have to worry about whether or not you’re in the right gear. You’ll realise right away how great automatic shifting is if you’re not a regular rider or if you need to come to an abrupt halt. The Shimano STEPS system will automatically shift down to a lower gear as you stop at traffic lights for example, then give you that extra surge when the lights go green for an easy start.

The motor and control system is the heart of any E-bike, and with Shimano’s intuitive, quiet and lightweight STEPS system, you’ll push boundaries and feel energised while doing it.


Yamaha are no strangers to motors obviously and every year build what’s close to half a million motors for e-bikes. Like the Bosch it’s a 250w crank drive motor with a 36v lithium ion 400Wh battery pack.

What’s different is the Yamaha battery bolts in from the side whereas the Bosch drips in front the top. Clearly the Yamaha version could allow for smaller frame builds to be possible.

The Yamaha battery features a small shock absorber to keep things quieter. It’s slightly heavier weight 2.9kg against 2.6kg Bosch but has a higher operating temperature plus gives more cycles on battery life, giving a very slightly higher average range with the battery. The Yamaha motor is designed to allow for the use of two chainrings up front and uses the square taper crank mount compared to ISIS on Bosch.



The latest offering from Yamaha is the PW-X motor is lighter, more compact and has more control over tuning. It has an integrated computer display but crucially it’s the increased number of pawls on the engagement which leads to a far more direct and responsive ride characteristic.

On climbs you can come to a standstill and yet still get immediate drive off the crank, something lacking on nearly all other motors. Unlike its stablemate the PW-X supports cadence of around 120 pedal strokes where the PW weakens after around 80. There’s also the extra power setting for super steep climbs. In short the display is better, the use is simpler and the power more subtle than the Bosch
