Tern Vektron S10 2023 Rider Review

The new 2023 Tern Vektron S10 folding bike has an almost infinite number of uses. Whether riding to work and having the versatility to fold the bike on or off a train, getting to work and tucking away under a desk or all round leisure riding, the new Vektron S10 can do it all.

The Schwalbe Big Apple tyres fitted as standard are suitable for both on tarmac and light forest tracks, bridle ways & canal tow paths. The folded dimensions are just 41x86x61cm, meaning it can even fit into the boot of a small hatchback!

Brakes & Gears

As is now standard on Tern folding electric bikes, Magura hydraulic disc brakes front and rear offer a user friendly, low maintenance experience whilst having enough stopping power to bring you and your cargo to a halt quickly!

Gearing on the Tern is provided by Shimano's Deore 10 speed drive train, for simple shifting both up and down hill.

Operated using a dual action trigger shifter on the handlebars, the Shadow+ rear rear derailleur keeps the chain taught even over bumpier terrain.

Wheels & Tyres

The Tern Vektron S10 is grips with decent Schwalbe Big Apple tyres which are designed for maximum grip whilst keeping rolling resistance to a low. More importantly they include kevlar lining protection to prevent annoying punctures.

The S10 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.

The bottom line..

Although compact, the wheel base is that of a regular bicycle, the handlebar, fork and overall geometry give for a nice smooth and comfortable ride whilst maintaining the practicalities of being able to pack this cargo bike away.

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 can't 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.

I took delivery of the bike last week. They gave me a thorough introduction and briefing on the bike. I have cycled 25 miles in Someset so far and I found the bike meets all my expectations. This is my first ebike experience and I cannot fault the bike so far. I am very happy with the choice.

Good service - seems efficient

Having had experience of the Bosch system, I chose this bike as it seems to be efficient and meets my needs for a local/holiday bike, though a little less weight & a 500w/hr battery would be useful. I have other bikes for off-road and for comfortable touring.

Very good, very small caveats

Brilliant, There isn't another bike that would do what this bike does, all the reviews on-line spell this out nicely. so just some small issues I have with it for sorting out on future models.
The Charger is quick, but heavy and huge, Bosch should integrate USBC trickle charge and discharge into the battery pack at this price, then you can keep it topped up at work and take it camping as stand alone power utility.
Its no Brompton, or anything like, if you need a small light Brompton like foldable with a motor, get one, this aint it.
The rear frame and rack is bit messy, with lots of TIG welding filler and bracing to make it work, although strong there seems a lot of metal bracing, other models are "cleaner' and more elegant in this area of the frame and rack.
My Ortieb panniers (20yo but still perfect) are not very secure on the rack, OK but easily dislodged.
The light is just OK, they will see you, but for €4K bike beam pattern is not up to modern accessory lights or as bright, could just be matter of an upgraded LED.
Folded its still big and handles like a set of angry bagpipes made out of pointy spikes, hower not a bad as some.
I would have prefered a Schwalbe tyre with more armour for puncture resistance.

I purchased this bike to use with my motorhome

I purchased this bike to use with my motorhome. I was unsure about being able to use it as I am 19 stone, 69 years old and suffer with long covid. After a few practice rides I got the hang of it. It became very easy and effortless to ride without becoming breathless. I feel like I have been rejuvenated.
