Carbon 1 ST vs Carbon Classic ST — same step-through ease, two ways to cruise

They share the Carbon family’s premium hardware, but each model leans into a different idea of what a “comfortable ride” should be.

Shared strengths — the Carbon ST DNA

Both the Carbon 1 ST and Carbon Classic ST are built on the same high-quality foundation, so you get the same core benefits whichever model you choose:

• Step-through Toray™ carbon frame — light, stiff, and easy to mount; perfect for skirts, casual clothing, or frequent stops.
• 750 W peak power — confident starts and steady climbs when you need them.
• 75+ mile real-world range (varies with assist mode, load, and terrain) — great for long errands or day trips.
• Featherlight weight (~38 lbs) — easy to lift for stairs, racks, or carrying into a café.
• Samsung 352.8 Wh battery chemistry — dependable cells for consistent range and battery life.
• Torque sensor — proportional, natural-feeling assist that responds to your pedal pressure.
• Premium components — puncture-resistant gravel tires, Tektro hydraulic disc brakes, and Shimano gearing for reliable, low-maintenance performance.
• UL certification — tested electrical safety on the major electrical systems.

both ST models give you the same light, capable, and safe Carbon experience — then add comfort features to make the ride feel like an effortless daily ritual.

Carbon Classic ST — comfort, simplicity, and practical control

The Classic ST is designed around the idea that comfort shouldn’t be complicated. If your priority is a calm, adaptable riding posture and easy control, the Classic ST makes it simple.

What’s special about Classic ST

• Thumb throttle — instant, gentle acceleration for quick starts or when you’re carrying bags. It’s practical for city riding and makes stop-and-go traffic effortless.
• 0–90° adjustable handlebar — switch from upright cruising to a sportier lean in seconds — perfect when you want to change posture between errands, rides with friends, or longer stretches.
• LCD display — a clean, distraction-free dashboard with the essentials (speed, battery, trip) so you stay focused on the ride.
• Comfort-first cockpit — a more relaxed bar sweep and a cushioned saddle option tuned for longer sit-times, helping reduce wrist and lower-back strain.

Why it’s great for comfort-seeking riders

• Easy on / easy off: the step-through frame and adjustable bars make the bike fit more body types and clothing styles without fuss.
• Control without complexity: throttle + simple LCD gives a gentle helping hand without needing to dive into apps.
• Practical for everyday life: quick starts, easy posture tweaks, and rack compatibility for grocery runs or a day out.

A note on security: AirTag option for Classic ST

If you prefer the Classic ST’s simpler cockpit but still want tracking, the Urtopia AirTag Kit is an easy add-on. It hides discreetly (inside the bell, under the saddle, or on the headset) and works with Apple’s Find My network for basic recovery support. It’s a practical way to add tracking without swapping to a SmartBox model.

Which ST fits you best?

Choose Carbon Classic ST if you want the most comfortable, uncomplicated city cruiser: effortless mounting, a throttle for practical starts, and an adjustable cockpit that adapts to your day. Ideal for riders who favor tactile comfort and everyday ease.
