Moustache J ON

The J ON is Moustache’s full-suspension city e-bike: a low step-through frame with a 100mm suspension fork and Moustache’s own 115mm rear air shock, built to take the edge off London roads. The stepless Enviolo hub is paired with a Gates carbon belt — no derailleur, no chain oil, and very little to maintain — and a Bosch Performance Line motor with a 625Wh battery provides a quiet, natural assist with generous range.

The Bosch Smart System brings the colour Kiox 500 display and app connectivity through eBike Flow, including eBike Lock, which stops the motor assisting until you unlock the bike from your phone or display. A dropper seatpost lets you put both feet down at the lights without leaving the saddle.

It comes fully equipped for daily riding: integrated lights, alloy mudguards, a rear rack with Ortlieb QL3 fittings, mudflaps and a kickstand. The frame is cast in one piece in France and carries a five-year frame and fork warranty. We have this bike in black, size M (suited to riders around 1.65–1.85m), available to view by appointment at our Camden shop.

A design-led, full-suspension city e-bike

The J is Moustache’s design-led city bike — a clean-lined, cast-frame step-through whose design won a Gold iF Design Award. The J ON is the on-road version, set up for the city and the smoother lanes beyond it.

What makes it special is how little it asks of you. Full suspension takes care of the road, a stepless Enviolo hub means there are no gears to choose, the belt drive needs no oiling, and the Bosch system handles navigation and security. It’s a bike designed to be ridden every day and thought about as little as possible.

An effortless bike to leave the car for

It’s for people who want a city bike that simply works — a car replacement for the commute, the errands and the weekend spin, with as little faff as possible. If you’d rather not change gear, clean a chain or worry about where you left the bike, the J takes all of that off your plate.

The low step-through frame and upright position make it easy and relaxed to ride in any clothes, the rack takes panniers or a basket, and a dropper post lets you put a foot down comfortably at the lights.

Full suspension, stepless gears and Bosch power

Comfort comes from full suspension: an SR Suntour fork with 100 mm of travel up front, and Moustache’s Magic Grip Control air shock at the rear, tuned to the frame so it stays smooth and composed over cobbles, kerbs and broken tarmac.

The drivetrain is the easy part: an Enviolo stepless hub that glides through its range with no fixed gears — just twist to find the effort you want — paired with a Gates carbon belt that runs clean and quiet and needs no maintenance. A Bosch Performance Line motor (75 Nm) and a 625 Wh battery drive it, with a colour Kiox 500 display and the option of Bosch’s PowerMore extender for longer days.

It’s finished for everyday use with integrated lights, full mudguards, a rack, a kickstand and a dropper post.

The J ON or the Mardi FS?

The J ON and the Mardi FS are both full-suspension city bikes, so it’s worth knowing how they differ. The J is the design-led option: a stepless Enviolo hub with nothing to click through, a colour display and a distinctive cast frame. It’s the one to choose if you want the bike to do the thinking, and to make a statement doing it.

The Mardi FS is the more understated, simpler choice, with a five-speed hub and a more classic look. If you value the design and the stepless, connected experience, it’s the J; if you want straightforward full-suspension comfort, it’s the Mardi FS.

They’re easy to ride back-to-back in our shops, which is the quickest way to feel which suits you.

FAQs

The J is Moustache’s design-led full-suspension city bike — a clean, cast-frame step-through whose design won a Gold iF Design Award. The J ON is the on-road version, set up for city streets and smoother lanes. What sets it apart is how effortless it is: full suspension, stepless gears, a maintenance-free belt drive and built-in connectivity, all in one distinctive package.

Instead of fixed gears you click through, the Enviolo hub changes ratio smoothly and continuously — you just twist the grip to make pedalling easier or harder, and it adjusts seamlessly, even at a standstill. There’s nothing to index or maintain, and paired with the belt drive it makes for a very quiet, low-effort ride. It’s ideal if you’d rather not think about gears at all.

It’s genuinely cushioned: full suspension front and rear, with Moustache’s Magic Grip Control shock, soaks up cobbles, kerbs and broken tarmac, and the wide Schwalbe Super Moto-X tyres add to that. The dropper post also lets you drop the saddle for an easy, confident foot-down at the lights. It’s set up for comfort on the road rather than off-road trails.

Not as standard on this bike, but it is ready for it: Bosch’s optional ConnectModule adds GPS tracking and a motion alarm through the eBike Flow app, and we can fit one for you. The Smart System’s eBike Lock is included, which stops the motor assisting until you unlock the bike from your phone or display.
