Compact, Stylish & British-Built 🇬🇧
The Synch Mini Monkey 250W may be compact, but it delivers big on power, style, and performance. Designed for riders between 5’0” and 5’6”, this hand-built UK electric bike offers a smooth, agile ride, making it ideal for city commuting, weekend adventures, or cruising through scenic paths.
Despite its smaller frame, the Mini Monkey packs a punch with a 250W Bafang rear hub motor, paired with a UK-manufactured 48V 16Ah battery, offering up to 40 miles of range on a single charge. With a quick 4-5 hour recharge time, it’s always ready for your next ride.
Handcrafted in the UK with British-Made Batteries 🇬🇧
Every Synch Mini Monkey is designed, built, and assembled in the UK, ensuring top-tier craftsmanship and quality. Unlike most e-bikes, Synch is the first electric bike company to use UK-manufactured batteries, supplied by Danecca, a specialist battery producer based in Silverstone.
