Bikesy's Verdict
Buy this Crossride e400B if you want a Bosch commuter that arrives ready for work, cycle paths and light touring, with lights, mudguards, a rear carrier, kickstand and a frame lock already fitted. The Active Line Plus motor, 500Wh battery and 80mm fork are there to ease everyday miles, not to stand in for a trail e-bike. Match the offer to the MY2024 build with the RST Blaze fork and Alhonga brakes, and sit on S, M or L in person before you decide. If that is your riding, it is worth comparing current UK offers.
Pros
- Bosch Active Line Plus motor with a 500Wh PowerTube battery
- Lights, full mudguards, rear carrier, kickstand and frame lock fitted
- RST Blaze 80mm fork and 29x1.75" mixed-surface tyres
- Alhonga hydraulic disc brakes with 160mm rotors
- Simple Shimano Altus 1x9 gearing
Cons
- Approximately 26 Kg makes stairs, some vehicle racks and frequent lifting awkward
- No published rider-height or inseam bands for the current S, M and L sizes
- Confirm whether the battery can be removed if you need to charge it indoors
The Rock Machine Crossride e400B is a Bosch mid-drive e-bike for commuting, city journeys, cycle paths and light mixed-surface touring. It suits a rider who wants a comfortable aluminium 29er with the useful kit already fitted, rather than a performance e-MTB. Front and rear lights, full mudguards, a rear carrier, kickstand and a frame lock come on the bike, so a commute or a towpath spin is ready to go.
The current UK offer is the MY2024 Crossride e400B Touring: a unisex MONO-frame bike in S, M and L, with an RST Blaze 80mm fork, Alhonga hydraulic disc brakes and a claimed weight of approximately 26 Kg. Use that specification when you compare offers. An older 2021 Crossride INT e400 B Touring had a different fork, brakes, weight and size range, and those details do not belong here. The manufacturer does not currently list this latest official version in its UK catalogue.
Motor, battery and range
The Bosch Active Line Plus is a 36V, 250W, 50Nm mid-drive with assistance up to 15.5mph. It is paired with an integrated 500Wh Bosch PowerTube battery, a Purion display and a Compact 2A charger. That setup is meant to take the edge off everyday miles and light touring, not steep trail riding.
Range is not a single tidy figure. The UK listing says up to 75 miles in the description and 70 miles in the specification table. Both are maximum claims, and they change with assistance mode, weather, terrain, tyre pressure and total load.
Weight, size and charging
Approximately 26 Kg makes stairs, vehicle racks and frequent lifting important to think about before you buy. Sizes are S, M and L, with no verified current rider-height or inseam bands, so confirm fit directly and do not use 2021 geometry as a stand-in.
The UK retailer marks the integrated battery as non-removable, but manufacturer evidence does not verify that. If indoor charging or taking the battery off for storage matters to you, confirm it before purchase.
Key Features & Benefits
- Shimano Altus 1x9: A straightforward 38T chainring and 11-36T cassette, with no front derailleur to fiddle with on the way to work.
- Rear carrier and pannier mounts: You can add compatible pannier bags for commuting or touring, once you have checked the carrier's load rating.
