New Features
The new 2021 Tern GSG Electric Cargo bike is latest evolution of an already highly popular cargo ebike - we're very pleased to be offering it in its new specification.
The GSD Electric Cargo bike comes as standard with built in mudguards, lights, and a large, high capacity load carrier - this new GSD had a max laden weight of 200KG!
Aside from it's bold colour scheme, the 2021 Tern GSD also now comes with the Cargo Line variant of Bosch's most powerful motor, with 85Nm or torque and up to 400% assistance.
The new 2021 version also now includes rear foot rests as standard, along with a full length chain and rear wheel cover to minimise any dirt/water throw from your rear wheel onto your cargo or small passengers!
Tern are well renowned for their reputable folding bikes. Having joined forces with Bosch in 2019, they bring a unique approach to the modern rider with their easily stowable electric cargo and commuter bikes.
The launch of such well made electric cargo bikes is great news for delivery riders, making last mile deliveries faster, easier, cheaper and cleaner!
What's your function?
The new 2021 Tern GSD electric cargo bike comes with a fantastic specification as standard, but it can be configured in so many ways to suit every individual rider or business' needs. The Tern GSD is enormously useful, but surprisingly small.
Picking the kids up from school? You can configure your Tern GSD with the Clubhouse Plus carrier, turning your Cargo ebike into a sustainable school taxi!
Looking to transport cargo? How about fitting your Tern GSD out with the short bed luggage tray to the rear or the transporter rack at the front, or both? Both are designed to fit standard sized Euro crates perfectly.
Everyday commuting? The Tern GSD can be equipped with their Cargo Hold Panniers and Rear short bed tray for the ultimate in carry ability with a weight limit of almost a quarter of a ton!
Front Transporter Rack
Made to the size of a Euro Container, easily add cargo to the front of your GSD.
Lower Deck Foot Plates
Lower deck foot plates offer support and confidence to passengers.
Cushioned Seat Pad
Cushion the rear rack to support passengers, use one per person.
Rear Short Bed Tray
Also fitting Euro Containers, add extra storage to the rear of your GSD.
More applications are available. Need something different to suit you? Just ask and we'll be able to assist.
Cargo Hold 52L Panniers
With a combined 102 Litres of storage capacity, the Cargo Hold Panniers can be used in "Roll Top" mode for a weather proof cargo option, or "Bucket Mod" for a full family sized weekly shop!
Clubhouse Plus Carrier
The included seat pad and backrest of the Clubhouse Plus carrier solution turn the rear cargo bed into a safe and comfortable, full protected space for your smallest passengers.
Storm Box
A useful addition to the Clubhouse, the Storm Box provides a good level of weather protection to the rear cargo, human or not! The Water resistant fabric will keep the worst at bay, whatever the weather!
Storm Shield
Part of the "Clubhouse Fort" range, the Storm Shield builds on the protection of the Storm Box for the Clubhouse seat, offering protection from wind, rain, snow and even UV. A cozy place for the little ones to ride or sleep.
Tern GSD S10 - Now fitted with Magura E-stop
The ebike revolution comes with very few drawbacks, but the single most often queried one is their weight. Its not often however, that prospective owners consider how this will effect the performance of the braking system. With a heavier bike, comes the need for a greater level of braking force and nowhere is this more important than on a bike designed to take a gross laden weight of 200Kg!
The Tern GSD uses a 4 part system, all with carefully considered and designed-in enhancements specifically for eBikes. The MDR-P rotors, sport brake pads and calipers are all honed in performance to offer the maximum amount of braking force right from their initial bite.
The final piece is the new Magura E-Stop brake levers. Both front and rear levers have rear brake light switches built in, so the second you grab a lever you're immediately signalling your intention to those behind.
All of the above are designed into the very core of the electrical and mechanical braking system of the bike and come as standard equipment on the S10 cargo ebikes.
The flexibility of the GSD Electric Cargo bike doesn't stop with the accessories. With the Tern GSD, you can even configure your battery and range to suit the planned journey.
The Tern GSD Cargo bike comes with a 400Wh Bosch PowerPack battery as standard, but is pre-fitted with the Bosch Dual Battery kit to instantly add a second. Any current generation Bosch PowerPack (not PowerTube) battery is directly compatible so if you already have a Bosch driven eBike with a 400 or 500Wh PowerPack battery, it can be dropped right in, or you can order a second along with the bike.
Cargo bikes are by nature, designed to carry increased loads which decreases range and so this level of flexibility "straight from the box" is both very unique, but great value and very useful!
The front chain ring and chain line is covered by Tern's unique chain guard, keeping you and any passengers clean in all conditions.
With the Bosch Cargo Line motor and batteries fitted within in the centreline of the bike, its a very well balanced machine - great if you have wriggly children on the back!
Also both sitting between the wheels keeps the balance and centre of gravity as low as possible for a nimble and responsive ride.
The German made centre kickstand supports the bike when not in use and allows easy loading of both luggage and small passengers. Its also able to be released by a newly designed lever system on the handlebars for a quick getaway!
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.
Couple the above with well spec'd components, it brings an overall great cargo bike for a mixture of uses & riding styles.
In fact, when not in use the Tern GSD can stand up on it's end and the handlebars fold down, this way it fits in elevators and takes up very little space footprint when stored.
The Tern GSD offers a unique approach to frame design. Fitted with a telescopic seat post and adjustable angle stem, it can accommodate riders from 4ft 10 through to 6ft 5.
One bike that can fit the whole family! Super adjustable.
The Tern GSD 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 Big Apple's are also designed to absorb the riding surface, giving a more comfortable overall feel for the rider.
All in all, the new Tern GSD electric cargo 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.
Bosch Cargo Line System
The new Tern GSD folding eBike features the latest Bosch Cargo Line crank drive motor, so you can be sure it's fitted with the latest kit and setup for optimum performance. Based on the Generation 4 Performance CX, this is the most powerful motor Bosch make!
This system outputs 85Nm of torque & peaks at 500w! It certainly packs a punch, it also offers up to 400% assistance on Turbo mode, while Eco mode offers a more subtle 50% assistance. There are 4 levels of assistance and remember you can always turn it off completely and ride it as a normal bike!
This machine rolls just the same as a normal cycle. In fact the quality in the design, geometry & build make it a true performer! The Tern GSD S10 allows for multiple batteries to be fitted as required - Offering complete control over and range anxieties.
Tern have equipped the new Bosch Purion display, a revised smaller dash that offers quick vision of essential parameters whilst occupying a minimal amount of cockpit space.
