When it got here out in 2017, the unique Tern GSD was one of the vital helpful e-bikes we’d ever examined. The brand new one is even higher. The body is stiffer, it may possibly carry heavier hundreds, and there’s a 70mm suspension fork now, making the newest GSD (get stuff finished) trip extremely clean whereas carrying heavy hundreds.
Each mannequin within the vary will get the Bosch Cargo Line motor, with 85 Nm of max torque and further assist at low cadences to get you off the road. The cockpit encompasses a excessive/low beam swap for the headlights and there’s even an always-on brake mild that intensifies if you squeeze the Magura MT5 eStop levers. That’s only the start of a protracted record of enhancements and design parts that may make you wish to transfer some cash round to place one in all these machines in your storage.
Odds are you got here right here to get the lowdown on each new function of the 2020 GSD, so we’ll lead with that. The efficiency and options of the $8,399 R14 earned it our Editors’ Alternative award, however we’re much more excited by the $4,599 base mannequin as a result of Tern did a wonderful job of sustaining many of the options throughout the three-bike GSD lineup. We’ll get into why the R14 mannequin prices a lot and whether or not it’s price it shortly.
The outdated GSD was already a stable, cargo-worthy bike, with a mixture of spherical and rectangular tubing that boasted a 400-pound gross weight restrict (rider and bike included). The brand new bike has wider, internally bolstered tubing, so the gross weight restrict is as much as 440 kilos. Tern slackened the seat-tube angle barely in order that the seat strikes even additional away from the handlebar as you increase it, growing attain for taller riders—a sensible replace on a one-size body. The brand new body additionally has built-in decrease decks that assist heavy panniers and provides passengers a spot to relaxation their toes. There’s a devoted trailer mount and, just like the final bike, this one stands on its rear finish to take up minimal ground area in residences and garages.
Suspension Fork and Seatpost
The brand new GSD will get a SR Suntour suspension fork that was custom-tuned for Tern. It has preload and lockout dials for on-the-fly changes, and we discovered that the fork makes the bike a lot simpler to regulate than the earlier one whereas driving over chunky pavement and rooty tow paths. In your backside, a Cane Creek suspension seat submit damps vibrations and supplies modest cushioning over bumps. You may even customise the seatpost suspension by swapping out the elastomer damper for firmer or softer choices.
Excessive Beams and Brake Lights
To make the GSD much more street worthy, Tern added a excessive/low beam headlight that peaks at 700 lumens for the R14 and LX fashions. The sunshine is actuated by separate buttons on the left aspect of the handlebar: an on/off button and a high-beam button. The latter permits you to rapidly flash the brights or go away them on. It’s also possible to regulate the angle of the sunshine by hand, which is useful for not blinding drivers, different cyclists, or pedestrians.
Tern additionally equips each mannequin with brake lights. They work no matter whether or not you may have the headlight and taillight switched on—squeezing the brake lever glints the sunshine on to alert close by street customers that you just’re slowing down. This function is a brilliant addition to road-going e-bikes—one which’s made attainable by the brake mild function of Magura’s comparatively new MT5 eStop brakes, so we hope to see it proliferate on different bikes quickly.
Lockstand and Abus Lock
In the event you use your GSD to buy groceries, you’ll desire a secure and handy kickstand and a technique of securing the bike whilst you’re away from it. So Tern launched the Atlas Lockstand, which routinely locks in place—merely stomp on one of many toes and push the bike backward to safe it. Whenever you’re able to trip, a lever on the handlebar unlocks it. It’s a slick and handy mechanism, solely marred by the truth that the toes aren’t far sufficient aside to maintain the bike secure on off-camber surfaces. The bike can even tip over in case you unload one pannier and go away the opposite pannier absolutely loaded—simply don’t try this, alright?
On the fork, an built-in Abus wheel lock secures the entrance wheel and makes the bike unrideable when engaged. We’d nonetheless suggest an extra body lock to stop your GSD from ending up behind somebody’s truck, however the sheer weight and measurement of the bike make it an unlikely short-term theft candidate for anybody with out a huge automobile to place it in and the power to elevate it (as I discovered hauling it up the steps to my condo). The important thing for the wheel lock stays within the keyway till you’re able to lock the bike—simply keep in mind to take it with you as a result of it’s additionally the important thing that removes the batteries.
Construct-In Chain- and Wheel Guards
A rear wheel guard is crucial for carrying youngsters, maintaining their toes from going into the spokes. Most cargo bikes solely provide them as an choice, however Tern places plastic guards on each side of the rear wheel. And whereas the outdated GSD had a partial chain guard, the brand new one has a full metallic chain guard to maintain your toes away from the chain or belt.
Which Model Is Proper for You
We bought the range-topping GSD R14 for our check, successfully the Rolls Royce of the e-cargo area. It options two Bosch 500 watt-hour batteries for a mixed 1,000 Wh—sufficient to go greater than 60 miles on Turbo mode and as much as 128 miles within the Eco setting. An enormous Bosch Intuvia show provides you easy-to-read metrics on velocity, battery life, torque output, and the present gearing of the Rohloff E-14 inside geared hub, which is linked to the crank through a Gates CDX Carbon Belt Drive.
I wouldn’t splurge on the R14 as a result of the in-between mannequin, the GSD S00, provides you many of the options for $2,400 much less. It comes with a single 500 Wh battery, though you’ll be able to spend extra to get a second one, and an Enviolo inside geared hub connects to the identical Gates belt drive. The Enviolo hub presents a smaller gear vary (380 p.c to the Rohloff’s 526 p.c) and isn’t fairly as environment friendly, robbing you of a in all probability imperceptible quantity of energy and a minor quantity of vary. The place you’d need the Rohloff’s 14-gear vary is throughout low-end grunt conditions like hill begins, however the Bosch motor has a lot torque that the majority of you received’t want the Rohloff’s smallest gears for something however insanely steep grades. Other than the hubs, variety of batteries, and show (you get the smaller Bosch Purion on the S00), the bikes are equivalent.
The bottom-model GSD S10 begins at $4,599. A Shimano Deore Shadow+ drivetrain takes care of shifting and the battery is all the way down to 400 Wh. If a low-maintenance belt drive is engaging to you—one you’ll be able to shift whereas at a cease—go for the S00. In any other case, the Deore Shadow+ drivetrain takes care of enterprise and saves you some huge cash. The suspension seatpost and headlight that come on the R14 are choices within the LX package deal for the S00 and S10; the LX package deal additionally ups the battery capability to 500 Wh for the base-level S10.
Panniers and Equipment
The flexibility to decorate a cargo bike to suit your wants is what makes it most helpful, and few bikes have extra out there equipment than the GSD. You may match a number of sizes of panniers; the biggest, at 52 liters, will maintain per week’s price of groceries. For hauling huge youngsters and adults, the brand new Clubhouse+ passenger enclosure supplies a safe enclosure for carrying youngsters, and the Captain’s Chair add-on serves as an adult-sized rear seat. There are additionally entrance and rear racks, trays, baskets, straps, and extra—discover the total record on Tern’s website.

We obtained our GSD R14 just a few days forward of the official launch, so what follows are preliminary impressions from just a few journeys to run errands. It’s a wonderful bike. The 20-inch wheels and low-standover body hold the burden near the bottom, minimizing the bike’s propensity to rock side-to-side if you make a sudden flip with added weight over the rear tire. The suspension fork makes the trip even smoother and the bike even simpler to regulate if you encounter tough pavement or gravel.
The Bosch Cargo Line motor continues to impress, with sufficient grunt to hold us up an 8 p.c grade at 15 mph with 40 kilos of groceries within the panniers. It’s additionally one of many smoothest torque-sensing pedal-assist methods available on the market, eliminating the jerkiness you get from lesser drive methods.
The Rohloff E-14 hub can be very slick: Two buttons on the precise aspect of the handlebar management up and down shifts via the 14 gears. Holding a button down for a second shifts you thru three gears directly, a useful function for getting in control or snap downshifts when the street kicks uphill. There’s a momentary dropoff in pedal help whereas the hub is shifting; to me, it felt longer than the dropoff you get from comparable chain-drive methods just like the Deore Shadow+ on the S10. By comparability, the Enviolo hub on the S00 has no dropoff whereas altering gear ratios and permits you to shift whereas at a standstill (though the Rohloff downshifts for you if you come to a cease). The profit to the Rohloff is the large gear vary and renown sturdiness below heavy load, however most GSD customers will likely be glad with the Enviolo hub or Deore Shadow+ chain drive.
For day-to-day usability, we love that the adjustable stem and telescoping seatpost enable a number of riders to make use of the GSD without having instruments to dial within the match. And vertical parking and the folding handlepost make it simple to slot in your front room or in an elevator.
Tern considered nearly all the things whereas redesigning the GSD. In the event you’re out there for a brand new cargo bike or kicking across the concept of a automobile substitute, this bike must be on the prime of your shortlist.
