FAQs
How far can I ride on a single charge?
In typical mixed riding, owners and retailers report 80–150 km per charge from the dual 48V 11.7Ah batteries (23.4Ah total). Expect the higher end with eco PAS on flatter routes and the lower end with heavy throttle, hills, or cold weather.
What’s the top speed, and is it road-legal in the UK/EU?
The X11 is commonly configured at 25 km/h to comply with EU/UK e-bike rules (EPAC). Some listings mention higher “unlocked” speeds for private land. Check your local regulations before altering speed limits.
What motor and battery setup does it use?
A rear-hub 250W motor (~500W/750W peak) paired with two 48V 11.7Ah batteries (total 23.4Ah), giving strong range and balanced weight.
Does it have hydraulic brakes and fat tires?
Yes. Retailers list hydraulic disc brakes front and rear and 20×4.0″ Kenda fat tires for grip on mixed terrain.
Is it okay in rain?
Listings cite IP54 water resistance—fine for light rain and road spray. Avoid submersion and pressure-washing; dry and store indoors after wet rides.
How long does charging take?
Retailers indicate roughly 5–7 hours depending on charger amperage and depth of discharge.
What’s the weight limit?
Most listings show ~120–150 kg max load. Check the exact figure on your unit’s label or retailer page as it can vary by batch and market.
Is it truly foldable and practical to carry?
Yes-folding frame for storage/transport. It’s a fat-tire bike, so expect a solid feel rather than ultralight; some shops list ~26–36 kg depending on configuration and accessories.
