Product Specifications
Quick Summary
The KETELES K820 Pro is a compact single-motor fat‑tyre e‑bike designed for everyday urban and trail riding. It's a versatile commuter that balances range and power in a user-friendly foldable package.
Smooth Power Delivery
The 250 W rear hub motor delivers steady pedal‑assist and throttle support, perfect for city streets or light trail use. Riders report smooth speed control and reliable performance across flat and rolling terrain.
Comfort & Control
Fat tyres and front suspension absorb bumps, offering confidence on uneven surfaces. Disc brakes provide reliable stopping power, and the Shimano 7‑speed drivetrain gives flexibility when accelerating or climbing.
Smart Battery System
A large 48 V 17.5 Ah removable battery ensures extended ride range. It locks to the frame and includes typical safety protections against over-charge and over-discharge for added peace of mind.
Tech You Can Trust
Full LCD display shows all key ride metrics—speed, distance, battery life, and assist level—making it easy to monitor performance and plan rides efficiently.
Built for Everyday Use
The folding frame allows for compact storage and transport. With its fat‑tyre stability, moderate weight, and reliable components, the K820Pro is a versatile option for daily commuting, errands, and casual off‑road fun.

Riders are advised to familiarize themselves with local laws and guidelines to avoid potential fines or penalties.
Electric Bikes (E-Bikes):
Electric bikes that meet UK government criteria (pedal-assisted, motor limited to 250W, and a maximum speed of 15.5 mph) are classified as Electrically Assisted Pedal Cycles (EAPCs). These can be used on public roads and cycle lanes without a license, tax, or insurance.
Riders must be at least 14 years old to legally ride an EAPC in the UK.
