Why this one
120Nm of torque is the number that matters. It is the maximum Bosch’s Performance Line CX delivers, and it means the steep lane you currently avoid becomes a road like any other. Behind it sits an 800Wh PowerTube — the big battery, the one that removes charge anxiety from a full day out — and Shimano’s XT 12-speed drivetrain doing the shifting.
What actually matters on this bike
The motor
Bosch Performance Line CX, tuned to a maximum of 120Nm. Torque is what you feel at the pedal the instant a climb bites: the gradient flattens, your cadence holds, and you arrive at the top breathing normally. The 800Wh PowerTube keeps that assistance coming all day.
The drivetrain and brakes
Shimano XT is the groupset riders upgrade to; here it is fitted as standard, twelve gears deep, crisp under full motor load. Shimano hydraulic discs on 203mm rotors front and rear give a 26.8kg bike serious, one-finger stopping power — controlled on wet descents, unflustered at speed.
What it is like to ride
A 100mm air fork and 2.6in Schwalbe Smart Sams take the sting out of rooty trails and broken tarmac alike, with the Purion 200 display keeping ride data in your eyeline. Assistance up to 15.5mph, no licence or insurance required — swing a leg over and go.

Questions about buying a bike from us
Do I need a licence, insurance or registration?
No. Assistance is capped at 15.5mph and 250W continuous, which makes this an EAPC — legally a bicycle in the UK. No licence, no registration, no insurance, no road tax, no helmet requirement. Riders must be 14 or over.
How far will it actually go on a charge?
Further on the flat, in a low assistance mode, with a lighter rider than any published figure assumes. We do not quote a range number because the honest answer depends on gradient, weight, temperature and which mode you ride in, and a single figure would be misleading in most of those cases.
How assembled does it arrive?
Around 90% built, on a specialist bike courier. Front wheel, bars, pedals and seatpost to fit. The battery ships part-charged, as regulations require — charge it fully before the first ride.
Can I ride it in the rain?
Yes. Motors and batteries on modern e-bikes are sealed against rain and road spray — check the IP rating on the manufacturer’s spec sheet for the exact figure on this model. What matters more in practice: never jet-wash an e-bike. The seals are made to keep rain out, not a pressure washer, and water forced into a motor is not a warranty claim.
Can I pay by finance or Cycle to Work?
No. Neither is available here, so the price you see is the price. Most UK e-bike purchases at this level go through one or the other. If that is how you were planning to pay, it is worth knowing before you get to the checkout.
Can I test ride one first?
Not with us — we are online only and hold no demo fleet. At this price it is worth sitting on one first: Specialized and Cube dealers run demo days, and the frame size you settle on there is the one we will supply. Send us the size and we will confirm it against the geometry chart before you order.
Who fixes it if the motor or battery fails?
The manufacturer’s warranty is handled through their dealer network, and a dealer is not obliged to prioritise a bike bought elsewhere. Tell us and we will open the claim and deal with the manufacturer ourselves rather than send you round the houses. Worth knowing before you buy from any online-only shop, including this one.
What happens when the battery wears out?
Batteries are a consumable. Expect meaningful capacity loss after several hundred full cycles, which for most riders is years rather than months. Both manufacturers sell replacements; that is a real future cost and worth knowing before you buy.
Kit it out
Bikepacking luggage straps to the frame, so it works on a bike with no rack mounts — which is most of these.
