Common questions
Is the Cyrusher Flex road legal in the UK?
Yes. It is a 250W electric bike whose motor stops assisting at 15.5 mph, which makes it an EAPC — legally a bicycle. You need no licence, no tax and no insurance, you can ride it anywhere a normal bike is allowed including cycle paths, and there is no helmet requirement. The rider must be 14 or over.
How far will the Cyrusher Flex go on one charge?
The manufacturer claims Up to 95 km (about 59 miles). Treat that as a ceiling rather than a figure to plan around: claimed ranges come from the lowest assist level on flat ground with a light rider, and hills, cold weather, tyre pressure and rider weight all take a bite out of it.
How long does the Cyrusher Flex take to charge?
About 8 hours from empty with the supplied charger.
How much does the Cyrusher Flex weigh?
31 kg. That is heavy. Fine to ride, but plan for ground-floor or shed storage: carrying it up stairs is a two-person job.
Can the speed limiter on the Cyrusher Flex be removed?
No — this model is locked at the UK assist limit with no setting to change it. In the UK, raising the limit takes the bike outside EAPC rules: it becomes a motor vehicle needing registration, tax, insurance and a helmet, it is no longer allowed on cycle paths, and an insurer will treat it that way after an accident. We record the setting because it decides what a bike can legally be, not to suggest you change it.
Does the Cyrusher Flex have a torque sensor?
It has both. A torque sensor scales the motor to how hard you are pushing, which feels like being a stronger cyclist; a cadence sensor delivers power whenever the pedals turn, which is less natural but easier going. Having both means you can pick per ride.
What brakes does the Cyrusher Flex have?
Logan fully hydraulic disc, 180mm front + rear. Hydraulic discs need less hand force and hold up better in the wet and on long descents than cable-operated ones. That matters more on a bike this heavy.
How much weight can the Cyrusher Flex carry?
158 kg (350 lbs), including the rider. Subtract your own weight to see what is left for luggage, a child seat or shopping.

Protect your new bike
Sort these three when it arrives and you reduce the risk of theft — a good lock keeps it safe, insurance covers you if the worst happens, and registration helps you get it back.
Lock — FoldyLock Elite
A super-flexible folding lock — easy to wrap around an eBike frame and lock to almost anything. The mount doesn’t rattle, and the key slides in and out and locks smoothly (plenty of locks don’t — it saves a real headache). We run the matching pair ourselves — two locks, six identical keys, so both our eBikes open with the same key — genuinely convenient. ART 3 / Sold Secure Gold rated, the certification level many insurance policies ask for.
Insurance — Bikmo

Register — Bike Register
Log your frame number on the UK national database the day it arrives — it deters thieves and hugely improves the odds of recovery.
