Meet Flex
Ready For The Route You Planned
And The One You Didn’t.
Flex is built for riders who want one e-bike to feel at home on city streets, cycle paths, compact gravel and light trails. It adds comfort where the ground gets rough without giving up the control and practicality an everyday ride needs.
BUILT AROUND THE RIDE
Comfort, Control and Freedom in One Frame.
The essentials work together so Flex feels composed on everyday roads and capable when the route becomes less predictable.
Choose the Route, Not the Category.
Flex is happiest where everyday roads meet the quieter way home.
CITY STREETS
Comfort over patched roads, speed humps and the rough edges of the daily commute.
BIKE PATHS
Relaxed miles on greenways, waterfront paths and traffic-free routes.
COMPACT GRAVEL
More reassurance when smooth pavement gives way to loose, uneven surfaces.
FOREST TRAILS
Explore maintained tracks and light trails without turning the ride into a technical challenge.
Mixed Terrain
Link road, path and trail in the same ride with fewer compromises.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.

Why It Rides Differently
Five Details You Feel on the Road.
Select a point on the bike to see how it changes comfort, control or effort.
Stay Composed Over Broken Ground
The front fork absorbs repeated impacts before they reach your hands, helping the front wheel feel more settled across broken roads, roots and gravel.
EXSHO Front Suspension Fork
Take the Repetition Out of Rough Roads.
The rear shock works with the fork to soften repeated impacts through the saddle and help the rear wheel stay more composed over uneven ground.
DNM AO-6 Rear Shock
Keep Momentum When the Road Tilts Up.
Rear-hub assistance supports climbs, restarts and changing gradients so you can manage pace with less strain.
250W Rear Hub Motor · Up to 87 N·m
Charge Where It Works for You.
The removable battery supports longer commutes and mixed-surface days while allowing flexible indoor charging and storage.
48V 15Ah Battery · 720Wh
Feel More Reassured When Pavement Ends.
The wider tyres add contact, cushioning and traction as the route changes from tarmac to compact gravel or maintained trail.

—— Dual Sensor System
Two Assistance Modes. One Bike That Adapts.
Use a natural response when you want the bike to follow your effort, or choose steady support when consistency matters more.
Natural Control
Easy Cruise
Natural Response
Push harder. Get more help.
Torque mode reads how firmly you press the pedals and adjusts support in real time. Starts feel intuitive, climbs feel easier to manage and the bike stays closely connected to your effort.
- Best for: Mixed terrain, changing gradients and riders who prefer a bicycle-like feel.
- Ride character: Responsive, progressive and closely matched to pedal pressure.
Steady Support
Keep turning. Let Flex carry the rhythm.
Cadence mode provides consistent assistance once the pedals begin moving. It suits relaxed cruising and riders who prefer predictable support without pressing hard through every pedal stroke.
- Best for: Level routes, easy cruising and a more relaxed pedalling style.
- Ride character: Simple, steady and easy to understand from the first ride.
Go Further on Every Ride.
Up to 95 KM of assisted riding with a removable 48V 15Ah battery. Actual range varies with terrain, assistance level and riding conditions.

MAXIMUM-RANGE CONDITIONS
— Confidence
Control You Can Trust From Start to Stop.
Braking, visibility and stable handling matter on every ride—not only when the trail gets rough.
Hydraulic Braking
Progressive stopping power gives you more control in traffic, on descents and when the surface is loose.
Integrated Visibility
Front and rear lighting help you see the road and remain more visible when daylight fades.
Stable Handling
Wider tyres and a composed chassis help Flex feel planted when the route becomes uneven.
Support After Delivery
Current warranty, returns, service and spare-parts information is available before purchase and remains accessible throughout ownership.
One Bike That Earns Its Space.
The value of Flex is not one headline specification. It is how many different rides it can replace.
— One Bike · Different Roles
RIDE TO WORK. TAKE THE LONGER WAY HOME. KEEP GOING AT THE WEEKEND.
Flex is built for riders who would rather own one adaptable e-bike than choose between an urban commuter and a light-trail machine.
Commuting
Regular road and cycle-path use
Local Errands
Short practical journeys
Fitness Rides
Selectable rider effort
Light Trails
Gravel and compact tracks
MORE USE FROM ONE PURCHASE
Road, path, gravel and light-trail capability gives the bike a broader role across the week.
CHARGE WHERE IT SUITS YOU
Remove the battery for indoor charging instead of planning every charge around the bike’s parking space.
FAMILIAR PARTS, FAMILIAR CONTROLS
A conventional drivetrain, hydraulic brakes and bicycle-style handling make Flex easier to understand and maintain.
Is Flex the Right Bike for You?
A versatile bike still needs to match the way you ride, store and handle it.
Flex makes sense when you want:
One bike for changing surfaces
Your usual route can include roads, paths, gravel and maintained light trails.
More comfort than a rigid commuter
You value reduced impact through the handlebar and saddle on rougher ground.
Choice in how assistance feels
You want natural torque response and steady cadence support in the same bike.
A removable battery
You need to charge indoors or want simpler battery storage.
A substantial, planted ride
You prefer stability and comfort over an ultra-light bike that is easy to carry upstairs.
Consider another style if:
You regularly lift the bike up stairs, need a low step-through frame, or plan to ride extreme technical or downhill trails.
ACCESSORIES
Set Flex Up for the Way You Ride.
Add carrying capacity, security or a spare battery when those needs are part of your routine.

Know Before You Ride.
Is Flex suitable for everyday commuting?
Yes. Flex is designed for city streets and cycle paths as well as compact gravel and maintained light trails. Its full-suspension construction makes it more substantial than a lightweight urban bike, so consider how often you need to lift or carry it.
What is the difference between torque and cadence mode?
Torque mode adjusts support according to how firmly you pedal, creating a more natural and responsive feel. Cadence mode provides steadier assistance once the pedals begin turning, which can feel easier and more relaxed on flatter routes.
Can the battery be removed for charging?
Yes. The 48V 15Ah battery can be charged on the bike or removed for indoor charging and storage.
Will every rider achieve 59 miles?
No. The 59-mile figure is a maximum assisted range under favourable conditions. Actual distance varies with assistance level, terrain, gradients, rider and cargo weight, wind, temperature, tyre pressure, stop-start frequency and riding style.
What terrain is Flex intended for?
Flex is intended for roads, cycle paths, compact gravel, towpaths, forest tracks and maintained light trails. It is not designed as a competition downhill or extreme technical mountain bike.
How should I choose the right size?
Use the final rider-height range, stand-over height and geometry published on the page. Riders between sizes should also consider reach, inside-leg measurement and whether they prefer a more upright or extended position.

I liked this bike so much that I bought two and adapted them to my needs, they are good strong bikes, look great and turn heads, they only had them in blue but that’s okay it’s a great colour.
I had an issue with one of the batteries and customer service was excellent, not only did they swiftly replace the battery but also sent me a pannier bag as a gesture of goodwill for the inconvenience the bike comes restricted to comply with UK law and a thumb throttle was included although not fitted. I would definitely recommend this company, beautiful bikes, excellent customer service, fast delivery and just all round a great deal….. five stars.
Thank you so much for sharing your experience with us! Welcome to Cyrusher Family!
D
my ebike was divered on time and I was very satisfied with the service I have not been out on it yet and I had a part in the box that I do believe it is a thumb throttle which I believe it can not be fixed to your bike in the uk i would appreciate eny feedback on this thank you.
We're delighted to hear that you like the bike, and we will help you out with the throttle issue, please check your email, our agent has sent you the video of setting up!

The weather was nice and beautiful today and I decided to hop on my xf800 for a nice ride. Still gets alot of compliments from people and the 20ah battery is definitely the best upgrade for the xf800. If you are on the fence about it, it's worth the money.
R
This wonderful cyrusher xf800 that I take everywhere with me (at the beach, for my work, for walks, even shopping).
