Suspension at both ends
A front fork and rear shock take the edge off potholes, gravel and light-trail chatter, making repeated uneven surfaces more comfortable.

Could your employer help you spread the cost? Cycle to Work
Many UK employees can get an e-bike through a Cycle to Work scheme, spreading the cost through payroll and potentially saving on tax and National Insurance.
Not sure if your employer offers one? It may be worth asking HR — many people are eligible without realising.

Your bike will arrive boxed and approximately 80% assembled. Some final assembly, adjustment and safety checks will be needed before your first ride.
Depending on the model, this may include fitting or checking the handlebars, stem, pedals or wheels, checking tyre seating and pressures, adjusting brakes and gears, and checking other safety-critical components.
Please follow the manufacturer's instructions supplied with your bike and make sure all required assembly, adjustments and safety checks have been completed correctly before riding.
If you're not confident carrying out the setup or checks yourself, we recommend asking a competent bicycle mechanic or suitably trained cycle professional to help.
You're responsible for making sure the bike is correctly assembled and safe to ride before first use. Problems caused or contributed to by incorrect assembly, adjustment or missed safety checks may not be covered as product faults.

About the Cyrusher Flex Full-Suspension Electric Mountain Bike
The Cyrusher Flex sits between a conventional city e-bike and an out-and-out fat-tyre machine. Its 27.5 × 2.6-inch Kenda tyres and front-and-rear suspension make it a capable comfort-focused choice for roads, towpaths and maintained trails, without the width of 4-inch fat tyres.
A removable 48V 15Ah (720Wh) battery feeds a UK-spec 250W rear-hub motor, with torque and cadence sensing to adapt the assistance to your riding style. Shimano 8-speed gearing provides familiar mechanical control. Cyrusher quotes up to 59 miles of range; our conservative planning estimate is around 38–52 miles, depending on terrain, assistance and rider load.
Hydraulic disc brakes, integrated lighting and a comfortable riding position round out the package. At roughly 31–32kg, the Flex is still substantial, and luggage racks and mudguards are accessories rather than standard bike equipment. It's an everyday mixed-surface bike, not a lightweight performance mid-drive trail machine.
Sizing & Fit
Cyrusher's detailed geometry chart recommends riders approximately 170–200cm tall, with 72cm standover, 43cm reach and an 88–96.5cm saddle-height range. Its separate summary guidance has also quoted 155–190cm, so the published recommendations conflict. Check actual inside-leg length and reach before ordering, and confirm fit with us if you're near the limits.
