Bosch Smart System Meets Daily-Speed Utility
The Ultimate T10 Smart System sits between Gazelle’s low-maintenance hub models and their high-speed belt-drive platforms. It uses a 10-speed Shimano Deore derailleur setup, giving a wide gear range, while still delivering upright Dutch stability and integrated commuter hardware.
The Bosch Performance Line motor (Smart System) gives controlled assist up to 20 mph. This is the Gazelle for riders who want more engagement than an automatic hub, more range flexibility, and modern ebike tech, but still expect Dutch reliability and all-weather durability — fenders, rack, lights, wiring, and stance all built in, not added on.

Bike Sizing, Simplified
Gazelle bikes don’t come in a dozen frame sizes like racing bikes — and that’s on purpose. Their upright, comfortable design and step-through frames let each size fit a wide range of riders. A more relaxed seat tube angle and higher handlebars mean that when you raise or lower the saddle, your leg reach and distance to the bars adjust naturally. In other words, one frame can fit people who are several inches apart in height. When choosing your Gazelle, the right size depends mostly on your height and preferred riding posture, not on fine-tuned racing measurements. Use the chart below to find your size — we’ll set up the saddle and handlebars so it feels perfect for you.
| Rider Height | Frame Size | Frame Label |
|---|---|---|
| 4'9"–5'2" | 40 | XS |
| 4'10"–5'6" | 45–46 | S |
| 5'6"–5'10" | 50–53 | M |
| 5'10"–6'3" | 55–57 | L |
If you’re between sizes, choose smaller for closer handlebars and larger for a bit more reach.
Fine-tune at pickup
We’ll set saddle height and handlebar angle for you in minutes. Expect about 4 inches of seatpost range for multi-rider households.
Step-through vs step-over
Step-through: easiest to get on and off. Step-over: slightly sportier feel.
