Synch Super Monkey 250W – Hand-Built in the UK 🇬🇧

Experience the perfect fusion of British engineering, power, and control with the Synch Super Monkey 250W Fat Tyre Electric Bike. Designed for riders who demand performance and style, this retro-inspired e-bike is built to order in the UK and offers a smooth, powerful ride on any terrain.

Uncompromising Power & Performance

Powered by a 250W Bafang rear hub motor, the Super Monkey delivers effortless acceleration, while the upgraded torque sensor provides instant power when you push the pedals, creating a more natural and intuitive riding experience. Paired with a Shimano 7-speed drivetrain, you can shift gears smoothly and adapt to varying landscapes with ease.

🇬🇧 UK-Manufactured Batteries – Built for Reliability

Unlike most e-bikes, Synch is the first electric bike company to use UK-manufactured batteries. Produced by Danecca in Silverstone, these 48V power packs are designed for optimal performance and longevity. Choose the optional 48V / 16Ah battery for up to 40 miles of range on a single charge, with a quick 4-5 hour recharge time.

Comfort & Control on Every Ride

  • Tektro hydraulic disc brakes for powerful and consistent stopping power.
  • Front suspension forks to absorb bumps and improve ride comfort.
  • Fat, puncture-resistant Synch tyres for superior grip and stability on all terrains.

Custom Colours & Accessories – Make It Yours

With Synch's custom colour option, you can make the Super Monkey uniquely yours—simply pick a shade from the RAL chart, and we'll build your bike in your perfect colour. Additional accessories, such as the LED front headlamp, are available as optional extras.

Designed, Built & Assembled in the UK

All Synch Super Monkey e-bikes are hand-built to order in Devon, UK, ensuring the highest level of craftsmanship. Each bike comes with:
✅ 2-year warranty on the frame and forks
✅ 1-year warranty on electrics

Production lead time: 2 weeks.

Please note the LED front headlamp is not included in the price and is an optional extra. 

 

How is the frame size measured?

Most E-bikes are measured from the centre of the crank to the base of the seat post tube. However, some E-bike manufacturers may measure their bikes differently depending on their style.
