Description
Range is not a specification. It is an argument about how far your day can reach. A commuter maths it in kilometres each way. A weekend rider maths it in how many trails sit inside a single charge. The Range Architect exists because those two people need the same machine: one that can carry real distance at real speed without asking to be charged every evening.
The arithmetic behind that is straightforward. A 48V 17Ah lithium pack feeds a 1000W brushless motor through a 60 to 70NM torque band, and the result is roughly 50 to 55 kilometres in pure electric mode or 70 to 90 kilometres with pedalling assistance across five levels. The pack is removable, so a bike parked in a stairwell does not have to be carried up to a socket. Charging from empty takes four to six hours on the supplied 2A smart charger, which means a pack refilled overnight is ready before the first ride of the morning.
Geometry and hardware decide whether those numbers are usable. A full-suspension aluminium frame with a lockout front fork absorbs the surface rather than transmitting it, SHIMANO hydraulic brakes give progressive stopping power that rim brakes cannot approach on a wet descent, and a 21-speed SHIMANO drivetrain keeps the rider in the efficient part of the cadence range even when the battery is left switched off entirely. The 27.5 by 2.4 inch CST tyres are the compromise that makes both tarmac and loose gravel viable, and the colour LCD reports speed, assistance level and battery state at a glance.
The road does not shorten. Your reach simply grows.

An electric bicycle earns its place when it replaces something else: the second car on a commute, the bus fare on a short trip, or the drive to a trailhead. This configuration is aimed at riders who want distance competence rather than novelty. Commuters with a 15 to 25 kilometre one-way trip can arrive without changing clothes and recharge in a few hours at a desk. Weekend riders get a machine that handles forest track and gravel without demanding a second bike for it. Anyone carrying loads benefits from the 150 kg load rating, and the adjustable geometry covers riders from 150 to 190 centimetres.
Frequently Asked Questions
Q: How far can it actually go on one charge?
Around 50 to 55 kilometres in pure electric mode, and 70 to 90 kilometres when the rider keeps pedalling across the assist levels. Terrain, rider weight, tyre pressure and how much climbing is involved all move those figures, which is why the honest way to plan a commute is to assume the lower number and treat the rest as margin.
Q: What is the difference between the 1000W and 250W versions?
The 250W variant carries a smaller 48V 10Ah pack and suits riders in markets that restrict motor output, or anyone who wants a lighter and more bicycle-like feel. The 1000W variant with the 17Ah pack is the long-range configuration, with noticeably more climbing authority and a higher top speed.
Q: Can the battery be charged off the bike?
Yes. The pack is removable, which is the practical answer for anyone who parks in a stairwell, a garage without power nearby, or an apartment building where running a cable outside is not an option.
Q: Is the top speed legally usable where I live?
The controller supports configurable limits, and the listing notes that lower speeds can be set to comply with local e-bike policy. Set the limit to the figure your jurisdiction allows before riding on public roads.
Q: How does it handle unpaved surfaces?
Full suspension, a lockout front fork and 2.4 inch tyres are the combination that makes loose gravel and maintained trails workable. The fork lockout is worth engaging on smooth tarmac, where a rigid front end is more efficient.
Q: What assembly is required on arrival?
The bike arrives largely assembled and needs handlebar, front wheel and pedal fitting, followed by a brake and gear check. Ordering the hydraulic-brake variant means the braking system is sealed and does not require cable adjustment afterwards.
Q: Does it ship from inside the EU?
Yes. EU spot stock dispatches from a France warehouse for EU orders, which avoids customs clearance on a large item and keeps delivery predictable.
