Tern Vektron Q9 2022 Folding Bosch eBike Shimano Rear Derailleur

Brakes & Gears

Fitted with Shimano MT200 hydraulic disc brakes front and rear, the Q9 is a user friendly, low maintenance experience whilst having the true braking power disc brakes bring.

Gearing on the Tern is provided by Shimano's Alivio 9 speed drive train, for simple shifting both up and down hill.

Operated using a dual action trigger shifter on the handlebars, the shadow rear mech offers the lowest profile 9-speed derailleur to help avoid knocks or damage when riding or stored.

Tern Vektron Q9 2022 Folding Bosch eBike Shimano Brakes

Shimano hydraulic brakes are light on the hands but hard on the discs when needed, making it a great option for ultra-urban riding.

Tern Vektron Q9 2022 Folding Bosch eBike Shimano Rear Derailleur

9 speed gearing in the form of the Shimano Alivio 11-32t group set is well balanced for on and light off road use.

Tern Vektron Q9 2022 Folding Bosch eBike Shimano Trigger Shifter

Alivio trigger shifters are quick, smooth and reliable, making this the perfect commuter bike.

Tern Vektron Q9 2022 Folding Bosch eBike Front Wheel

Wheels & Tyres

Kintex 20" wheels small enough to allow the bike to be easily stowable, but larger than most folding bikes and offer much greater stability and a larger contact patch with the ground. They're laced onto Shimano quick release hubs, making wheel removal a breeze.

The Tern Q9 comes equipped with Schwalbe Big Apple 20"x2.1" tyres. An excellent all purpose option, being a 20" wheeled bike there is a huge crossover with other styles of bike and so future tyre options are vast. More importantly they include the kevlar lining protection to help prevent annoying punctures.

Tern have developed a fully built in LED lighting system front and rear. Completely powered off the Bosch system there is no need to carry bulbs, batteries, and they cant be easily stolen and reused.

The new Tern Vektron electric folding bike ticks the boxes for those looking for a nice ride and neat solution to travel and storage. A nice simple, but good quality electric bike, suitable for a mixture of riding styles and rider heights.

tolerable coffee and plenty of bike porn to

this is now ebike #3 from Martin and the crew, fantastic service, tolerable coffee and plenty of bike porn to look at after i've finished shopping for what i need. As usual Martin listened to what i wanted to use the bike for, and then recommended the most appropriate solution (which wasn't the most expensive :) )

the tern is a great bike, i use it for the end of a commute in london after parking up, it is a little bigger and heavier than say a non motorised brompton, but, and its a big but, it rides like a normal bike - no twitchiness, no wobbling, quick and direct steering, and goes like stink. Having ridden and owned hub and crank drive bikes, there is no comparison, assistance is quick, direct and torquey.

the other to mention is the adjustability and flexibility - this bike adjust in seconds (bars and seat) to be comfortable for me (6'1 and too many kg) or my wife (5'2 and not) it also happily tows my little boy on his trailer bike, carries a laptop and a projector, fits in the lift and under the desk at work, and has lights, mudguards, a clever bungee system, and a chain tucked well out of the way so i happily ride it in a suit. Equally it's at home as part of our campervan travelling down gravel paths, old railway lines and the like.

i'd reccomend this bike for anyone looking for a high quality, reasonably priced folder or even hybrid use bike.

thanks!

In use for 2 weeks now for daily commute

In use for 2 weeks now for daily commute. Very pleased so far with the Bosch motor, the overall concept of the bike - rock solid and stable, with very good quality components. The only thing I miss is a slightly longer handlebar stem, better suited to my height - but the adjustability is a great plus - anyone between 150cm up to ca. 200cm height could ride this bike!
