Tern Vektron P7i Folder
The Tern Vektron P7i is a 20″ wheel, fully folding electric bike, powered by Bosch. Designed for a multitude of uses, the Vektron P7i is equally at home in the urban jungle or on the boat, caravan or motorhome.
Almost identical to its sister, the Vektron Q9, the P7i has hub gearing rather than derailleur.
Powered by Bosch’s Active crank drive motor, the Vektron P7i delivers a smooth and energetic pull on the hills. The large 400Wh battery ensures more than ample range for all journeys. This little beast will provide endless hours of enjoyment. It’s so portable, and simple to fold. It’s lightweight aluminium frame ensures strength as well as maneuverability. A simple yet reliable mechanism known as the ‘OCL+™ Frame Joint’ allows the Vektron P7i to become half its size in a matter of seconds. This unique piece of engineering is so strong that it exceeds ISO 4210 and EN 15194 testing requirements. The Vektron P7i uses ‘N-Fold™ Technology’ allowing a complete and fast fold in three easy steps. Retaining straps ensure the bike stays folded. Nothing could be simpler. Furthermore, with the handlebar folded to the outside of the package, the Tern can also roll when folded for easy transport.
Smart folding mechanism
Part of the Vektron P7i’s genetic makeup features an ‘Andros™ Stem’. This is Tern’s own unique adjustable stem that allows the rider to rotate and set the handlebars as required without the need for tools. It takes seconds to adjust, and means the bike’s geometry is a perfect fit for all. A telescopic seat-post ensures further flexibility. There’s more clever design too with a special saddle that allows the user to carry the bike comfortably via the shoulder. The underside of which has an integrated shoulder pad that also acts as a grip when rolling while folded.
It has its own side-stand as well as an ‘A’ support underneath the motor on which to rest the bike in its folded state.
Gearing is via Shimano’s Nexus 7-speed hub. Changes can be made easily whilst stationary and are maintenance free, unlike derailleurs. Braking is highly effective thanks to the Shimano hydraulic disc brakes front and rear, and ensure the Vektron P7i responds when asked. Keeping the rider fully comforted are the highly absorbing Schwalbe Big Apples. No need for suspension forks on this little gem! These huge balloon tyres ensure every bump and hollow are effortless. Velo ergonomic grips enhance rider comfort and support the hands precisely.
Lighting is provided via a powerful 41 lux, 150 lumen Valo Direct lamp sited inside the handlebar stem. This ensures it’s safe from knocks, bumps, and theft as well as being protected while folding. The Bosch Purion LCD mounted to the left of the bars provide clear and succinct rider information. Bosch drives have four levels of power assistance that are easily changed.
Closely related to the P7i is the superior spec Vektron S10 with derailleur gears that has rave reviews:
August 2017 Electric Bike Action Magazine review of the Tern Vektron S10. Their verdict was glowing:
“Tern has hit this one out of the park. This is one of the most impressive folding bikes we’ve ridden, both in terms of build quality and components, as well as ride quality. It’s not aimed at the bargain hunter; but meant for riders who want quality, durability and fun. It’s a great commuter, but it’s also a great travel bike.”
