Tern builds two very different things: electric longtails that can replace a car, and folding bikes that fit in a boot or on a train. In between sit about ten families, four overlapping frame generations, and an accessory catalogue where the same name exists in a "regular" and a "Mini" version — and the two do not fit the same bikes.
This article sorts it out. For each family: what it is for, what it carries, and above all which accessories our customers actually order with it — not a theoretical option list, but what has left the Liège workshop across the 57 Terns we have delivered to date.
Prices incl. VAT from the KAMEO catalogue on 22 September 2026, all model years combined. Load, weight and standards figures come from official Tern spec sheets. Order frequencies come from our own deliveries and are only indicative for the families with enough volume.

Four worlds, not ten
The range looks dense as long as you read it model by model. Read by use, it fits into four blocks.
The electric longtails
→ GSD and Quick Haul Long — two children or one adult on the back
→ HSD and Quick Haul — one passenger, the footprint of a normal bike
Off-road and city
→ Orox — the cargo bike that leaves the tarmac, 27.5 × 4" or 29 × 2.6" tyres
→ NBD — extra-low frame, 39 cm step-through, designed for accessibility
The electric folder
→ Vektron — Bosch, folds in 10 seconds, built for train + bike travel
The non-electric folders
→ Link (versatile) · Verge (451 wheels, quick) · BYB (double fold, the most compact)
→ Eclipse (26" wheels) · Node (24" wheels)
One point of vocabulary that prevents a lot of ordering mistakes: at Tern, the version suffix describes the drivetrain, not the trim level. D = derailleur, P = performance, S = Bosch Smart System, R = Rohloff hub, i = internally geared hub. An HSD P5i and an HSD P10e therefore share the same frame and the same motor: only the drivetrain differs.
The longtails: carrying without a car
This is the heart of the range and, for us, the bulk of Tern sales. Four families, separated by a single question: how many people ride on the back.
The car replacement. Bosch Cargo Line motor, two battery bays up to 1,600 Wh, 210 kg max gross weight, two children or one adult on the back. It parks upright and fits in a building hallway.
The length of a normal bike, the capacity of a cargo bike: 190 kg max gross weight, one passenger, rack certified to 80 kg. This is the Tern that stores away most easily — 166 cm folded.
The way into compact cargo. 150 kg max gross weight, 50 kg on the rack, 23 kg on the scale. One child, the groceries, and a 49 cm step-through that makes it easy to get on.
Two children without stepping up to the GSD. Bosch Cargo Line motor, 190 kg max gross weight, Atlas L rack rated to 90 kg. It takes the large GSD accessories, not the HSD ones.
The cargo bike that leaves the tarmac. Bosch Performance CX, up to 1,600 Wh, 27.5 × 4" or 29 × 2.6" tyres, two frame sizes. 210 kg on the road, 180 kg off-road.
39 cm step-through, suspension seatpost, 20" wheels. This is not a cargo bike: it is the Tern for people who want to get on and off without lifting a leg. 140 kg max gross weight.
What our customers actually order with their longtail
The figures below are ours: bikes delivered per family, and how many of them left with the accessory. We have excluded wear parts — brake pads, inner tubes, tyres — which top every list and say nothing about real needs.
GSD — 19 bikes delivered
12 of 19 Thule Yepp Nexxt 2 Maxi child seat, rack-mount version — the seat Tern recommends on the GSD
9 of 19 Clubhouse (€249.95) — the rail that turns the rack into a passenger compartment, two children
8 of 19 Transporteur Rack (€174.95) — frame-mounted front rack, 20 kg, the load does not turn with the bars
8 of 19 Clubhouse Seat Pad (€34.95) — the seat cushion, almost automatic once there is a Clubhouse
6 of 19 Storm Box (€254.95) — the hard case that takes the Clubhouse's place when you carry things rather than children
6 of 19 Clubhouse Backrest (€39.95) — the backrest, for the rides where the child falls asleep
5 of 19 Abus Bordo 6500K/120 folding lock, ART 2 rated — often paired with an adapter chain to tie the bike to a fixed point
3 of 19 second Bosch PowerPack battery in the spare bay, and front Hauler Rack (€149.95, requires the Luggage Truss CMT at €64.95)
HSD — 20 bikes delivered
9 of 20 Transporteur Rack (€174.95) — the same one as on the GSD, the most universal accessory in the range
7 of 20 Sidekick Footrests (€54.95) — fold-out footrests, HSD Gen 2 and Gen 3 only
6 of 20 Sidekick Wheel Guard M (€29.95) — the rear wheel guard, essential as soon as a child puts their feet next to the wheel
6 of 20 DuoStand Gen 3 (€134.95) — double kickstand rated to 80 kg, which changes everything when loading a child at a standstill
5 of 20 Captain's Chair Gen 2 (€249.95) — the seat for a bigger child, an alternative to the Clubhouse Mini (one or the other, not both)
4 of 20 Clubhouse Mini (€149.95) — the one-child rail, HSD / Quick Haul format
4 of 20 Cargo Hold 28 (€89.95) or Cargo Hold 37 (€219.95) panniers — Fidlock mount, compatible with a child seat in place
2 of 20 Storm Shield Mini (€234.95) — the rain canopy, and a Quad Lock Out Front Pro phone mount
Quick Haul — 11 bikes delivered
4 of 11 Abus Granit XPlus 6950M lock — the reference lock on this format
3 of 11 front Hauler Rack (€149.95), Clubhouse Mini (€149.95) and Sidekick Stirrups (€59.95) — the stirrup footrests, the Quick Haul version of the Footrests
2 of 11 Transporteur Rack, Captain's Chair Gen 2, Sidekick Wheel Guard M and RidePouch (€29.95), the small frame bag
Worth flagging even though it does not show up in the orders: the Glovebox (€54.95) is a storage bin that only fits the Quick Haul. It is the only enclosed storage in this format.
Quick Haul Long, Orox, NBD: too little data
We have delivered 3 Quick Haul Long and 1 Orox. Too few for an honest ranking, so we are not publishing one.
Instead, the compatible kit: Clubhouse (large format, €249.95), Cache Box L (€84.95, Quick Haul Long only), Stow Decks (€144.95) and Sidekick Wheel Guard L (€44.95) for the Quick Haul Long.
For the Orox: front Trail Rack (€139.95), Cargo Hold 72 panniers (€294.95, Orox only) and dedicated X27.5 or X29 mudguards (€64.95) depending on wheel size.
For the NBD: the DuoStand S (€94.95) is the only double kickstand approved on this frame.
The folders: the bike that gets on the train
This is where Tern started. Five non-electric families and one electric, separated by wheel diameter and folded volume.
The only electric folder. Bosch motor, 400 or 545 Wh battery, folds in 10 seconds, 22 to 24 kg. Built for train + bike commuting and flats without a basement.
The most versatile and most affordable folder in the range. 20" wheels, 12 kg, Andros stem adjustable without tools. The right choice for a first folding bike.
The folder that rides fast. Deep-section 451 wheels, T-Tuned geometry, down to 10.2 kg on the X11. For people who cover distance, not just the last mile.
The most compact, thanks to a double fold: 35 × 81 × 52 cm on the P8. For when the constraint is not weight but volume — car boot, cupboard, under a desk.
26" wheels: a folder that rides like a full-size bike. The opposite trade-off to the BYB — bulkier folded, far more comfortable over distance.
24" wheels, between the Link and the Eclipse. Integrated Nexus 7 hub on the D7i, 25 kg rack. The folder for those who find 20" tiring and 26" too bulky.
On accessories, folders follow a completely different logic from longtails: you are not after capacity but less bulk and more comfort. The recurring workshop requests:
Carrying and storing
→ AirPorter Slim (€319.95) — the hard case for putting the bike in the hold
→ Metro Transit Rack (€79.95) — 20 kg rear rack, designed for the BYB
→ Luggage Truss CMT (€64.95) + Hauler Rack (€149.95) — the front rack that does not turn with the bars
Comfort and fit
→ Physis 3D T-Bar Handlepost (€159.95) — the telescopic handlepost, in 290, 320 or 350 mm
→ Telescopic Seatpost (€69.95) — in 33.9 or 34.9 mm, to be checked against your frame
→ MKS UB-Lite EZY (€104.95) — quick-release pedals, to save the last few centimetres
Everyday equipment
→ mudguards in the right diameter: 451 for the Verge (€39.95), SKS Mini 20" 406 for Link and Vektron (€44.95), MTR for the BYB (€54.95)
→ Valo 2 (€74.95) — the front light running off the dynamo or the bike battery
→ RidePocket (€39.95) — the handlebar bag, and Bossless Bottle Cage (€32.95) for a bottle cage where the frame has no bosses
The three compatibility traps
This is where most returns come from. Tern names its accessories by function, not by bike: two products with near-identical names can have nothing in common.
1. "Mini" is not a size, it is a bike family
→ Clubhouse Mini, Storm Box Mini, Storm Shield Mini, Sun Shield Mini, Cargo Lid Mini → HSD, Quick Haul, Short Haul
→ The versions without "Mini" → GSD, Quick Haul Long, Orox
A Storm Box bought for an HSD will not mount. Nor will the reverse.
2. Weather protection stacks in a fixed order
→ The Rain Shield does not attach to the bike: it clips onto the Sun Shield, which itself requires the matching Clubhouse.
→ Same chain in Mini form: Clubhouse Mini → Sun Shield Mini → Rain Shield Mini.
Three purchases, not one. Real budget for a full canopy: count the Clubhouse on top of the cover.
3. The rear rack takes only one platform
→ Clubhouse Mini or Captain's Chair, never both.
→ A rack-mount child seat occupies the same space: on an HSD, a Yepp Maxi seat and a Clubhouse Mini compete for the same rail.
The right question in the shop is not "which accessory", it is "who rides on the back, and at what age".
One last, less obvious point: frame generations overlap in the catalogue. Sidekick Footrests are made for the HSD Gen 2 and Gen 3; a Clubhouse Gen 3 only fits the GSD Gen 1 and Gen 2. Before ordering a part for a bike you already own, give us the year and the exact version — that is what settles it.
How to choose
One child or two?
This is the question that splits the longtail range in two. One child: HSD or Quick Haul, with a Clubhouse Mini or a Captain's Chair. Two children: GSD or Quick Haul Long, with the full-size Clubhouse. Moving from the "one" format to the "two" format later means changing bikes, not just accessories.
Where does the bike sleep?
Every Tern longtail parks upright — that is the point of them. A folded HSD is 166 cm long and fits in a hallway; the GSD, at 182 to 185 cm, asks for a bit more. If the bike has to go up stairs or into a lift, say so before choosing: that criterion rules out more models than motor power does.
Do you need the second battery?
On the GSD and the Orox, the second bay doubles the range. Three of our nineteen GSD customers took it. It is worth it if you ride more than 50 km a day loaded, or if you cannot charge at work. Otherwise it adds weight and cost for range most people never reach. It can be added later.
Folder: which wheel size?
Folded volume and ride comfort pull in opposite directions. BYB (20", double fold) for minimum volume; Link and Verge (20" and 451) for balance; Node (24") and Eclipse (26") if you ride more than 10 km at a stretch. A test ride settles in five minutes what a spec sheet never will.
Can accessories be added later?
Almost all of them, yes — that is the principle of the Tern system. Two exceptions to plan for: the double kickstand (DuoStand, Atlas) is fitted with the crank removed, so it is better ordered with the bike; and the battery bays are part of the frame, they cannot be added. Everything else bolts on in a single workshop visit.
Unsure about compatibility?
The catalogue is online, and the Liège workshop checks the fit with you, model and generation in hand.
