OROX S12 · 27.5" · 1×12
Orox S12 (27.5")
All-season, all-terrain electric cargo bike — haul two kids, a passenger, or a full load, anywhere.
The Tern Orox S12 is a purpose-built all-terrain electric cargo bike designed to go where most cargo bikes won't. Powered by a Bosch Performance Line CX motor with up to 85 Nm of torque, fitted with fat 27.5" Vee Snow Ball tires, and EFBE-certified to carry up to 210 kg on pavement, the Orox S12 is as capable on trails and snow as it is on city streets. The Shimano Deore XT 1×12 drivetrain, Magura 4-piston hydraulic brakes, and dual-battery readiness make it one of the most serious cargo haulers available — at any price point.
Highlights
Bosch Performance Line CX motor
Up to 85 Nm of torque and 340% support ratio. This is Bosch's flagship cargo motor — built for steep climbs and heavy loads without breaking a sweat.
Dual-battery system — up to 1450 Wh
The standard 725 Wh battery delivers up to 146 km of range. Add a second battery for up to 292 km — enough for multi-day touring or truly long hauls.
Shimano Deore XT 1×12 drivetrain
A 12-speed Deore XT Shadow+ rear derailleur paired with a 10–51T cassette delivers a massive gear range — climbing loaded or descending fast, shifting is always precise.
Magura MT5 4-piston hydraulic brakes
Front and rear 203mm rotors with Magura's powerful MT5 levers and calipers. Fully loaded stops from speed require serious brakes — these deliver.
Vee Snow Ball 27.5×4" tires
Stud-compatible fat tires that handle dirt, gravel, snow, and wet pavement. The Orox lives up to its all-terrain promise right down to the rubber.
EFBE-certified for 210 kg GVW
Certified to carry up to 210 kg (462 lb) gross vehicle weight on pavement and 180 kg (397 lb) off-road. Carry two child passengers, an adult, or a full load of cargo with confidence.
Bosch Smart System with ConnectModule
Built-in GPS/GSM connectivity with eBike Alarm and eBike Tracking when subscribed to Bosch Flow+. Includes a free 12-month trial upon activation.
Bosch Kiox 300 colour display
Bosch Kiox 300 or Kiox 500 (smartphone holder) — splash-proof colour display with LED remote and integrated electronic bike lock. Full control of your ride, ride data, and settings at your fingertips.
Atlas X ultra-heavy duty wheels & rack
Tern's own Atlas X wheelset features CNC hubs with disc cooling fins and Boost thru-axles. The Atlas X rack is rated to 100 kg (220 lb) of cargo capacity.
Ignis 700-lumen headlight + G-sensed brake light
Ultra-wide Hi/Lo beam headlight for genuine trail visibility, plus a rear brake light that activates automatically when you slow down.
ToughShield self-healing paint protection
Factory-applied ToughShield film on the top tube and downtube protects the frame from chips and scratches — and heals minor marks on its own.
