A versatile Bosch electric bike for £1,799

At its original £3,099 price, the Rock Machine Crossride e400 B Touring faced plenty of accomplished competition. At £1,799, however, the complete package becomes considerably more attractive.

The biggest reason is its Bosch electric-assistance system. The Bosch Active Line Plus motor produces 50Nm of torque, which should provide smooth and natural support for everyday journeys, rolling country lanes and moderately steep climbs.

It is not the most powerful Bosch motor available, so riders searching for aggressive electric mountain bike performance may want something stronger. For commuting, touring and mixed-surface leisure riding, however, its quieter and more measured assistance is arguably a better fit.

Power comes from a fully integrated 500Wh Bosch PowerTube battery. Rock Machine quotes a maximum range of up to 75 miles, although real-world range will depend on the assistance mode, hills, temperature, surface and how much luggage you carry. Even with those variables considered, 500Wh is a useful battery capacity for regular commuting and longer recreational rides.

Comfortable on roads, paths and light gravel

The Crossride sits somewhere between a trekking bike, commuter and leisure-focused electric hybrid. Its aluminium MONO tube frame uses Rock Machine’s Cross Fun Geometry, designed to deliver a comfortable and controlled riding position.

An RST Blaze suspension fork with 80mm of travel helps absorb potholes, rough cycle paths and compact gravel. The 29-inch WTB Riddler tyres provide a good compromise between efficient road rolling and additional grip on looser surfaces. Their reflective sidewall stripe also improves visibility when riding in poor light.

This does not turn the Crossride into a full electric mountain bike, but it makes it more versatile than a rigid urban e-bike. It should suit riders whose journeys include a combination of tarmac, towpaths, cycle trails and well-maintained forest tracks.

Straightforward Shimano gears and hydraulic brakes

The Shimano Altus 1x9-speed drivetrain keeps gear selection simple, with no front derailleur to manage. Its 11-36T cassette provides a practical spread of gears for everyday riding, while the Bosch motor supplies additional support when the road begins to climb.

Altus is an entry-level Shimano groupset rather than a premium option, but it is widely used, relatively straightforward to maintain and perfectly suitable for commuting and leisure use.

Alhonga hydraulic disc brakes handle stopping duties. The 160mm rotors should provide reliable braking in wet and dry conditions, an important consideration on a heavier electric bike or when riding with luggage.

Ready for commuting and touring

One of this bike’s biggest advantages is how much equipment comes included. The Crossride e400 B Touring is supplied with:

  • AXA front and Spanninga rear lights

  • Full-length alloy mudguards

  • Alloy rear luggage carrier

  • Kickstand

  • AXA Atlas frame lock

Buying and fitting these items separately could add a meaningful amount to the cost of a basic electric bike. Here, the Crossride is ready for daily transport or touring almost immediately.

The rear carrier provides space for panniers, while the mudguards make the bike much more practical throughout a typical British winter. Integrated lights also mean there is less need to remember separate rechargeable units.

Who is the Rock Machine Crossride e400 B for?

This electric bike is particularly well suited to riders who want one machine for several different jobs. It could be a strong choice for:

  • Daily commuting and utility journeys

  • Weekend leisure rides

  • Cycle paths, towpaths and light gravel

  • Carrying panniers or shopping

  • Riders wanting established Bosch motor and battery technology

  • Anyone searching for a well-equipped electric bike under £2,000

Dedicated mountain bikers may want a more powerful motor, wider tyres and a stronger suspension fork. Road-focused riders may also find a rigid hybrid lighter and more efficient. The Crossride’s appeal lies in its versatility rather than specialisation.

Velostrive verdict
