Description
The Vektron P5i Folding Electric Bike (Gen 4) is a proper Bosch folding e-bike: small when parked, solid when riding.
PLEASE NOTE. AS OF June 2026 as far as we are aware, every dealer in the UK has sold out of their allocation of these bikes (including us) until November 2026 when the next container ship arrives. If you wish to pre-order one for then, we are able to offer a pre-order discount. Other than that we can do some offers on other models of the Vektron. Call us on 0208 347 5534 if you’re interested.
Belt drive + internal gears for low-faff commuting.
The Vektron P5i is Tern’s flagship folding e-bike, and it’s the one that makes you forget it folds. The Bosch Performance motor puts out 75 Nm of torque — more than enough for North London’s hills — paired with a Gates Carbon belt drive and Shimano Nexus 5-speed hub so there’s no chain to degrease and no gears to faff with. The PowerPack 400 Wh battery gives you a realistic 40–87 km of range, depending on how heavy your shopping is. Magura hydraulic disc brakes stop it properly in the wet. The Atlas V rear rack takes up to 27 kg of load. It fits riders from 4’10” to 6’5″. And it folds to a roll-upright package in 10 seconds flat — manageable enough to wheel through a tube barrier or slide into a car boot.
It runs on Bosch Smart System, which means eBike Lock, over-the-air updates, and compatibility with the eBike Flow app. Add the optional ConnectModule if you want GPS tracking and Smart Alarm.
Colour: Urban Verdant.
We build and set up every Vektron properly before it leaves the shop, and we carry spares and the know-how to keep it running. Pop in, or drop us a message to book a test ride. Cycle to Work schemes accepted — most of our customers save 42–47%.
