Boasting sleek Swiss designs and some innovative electronics, Stromer is a company e-bike fans will definitely want to keep an eye on. Bikerumor has checked out two Stromer e-bikes before, the ST2 and the ST2 S, but with a price tag of $9500 the ST2 S is a bike most of us will only read about for curiosity’s sake.
The new ST1 X couldn’t be called cheap, but at just over half the price of the range-topping ST2 S it’ll be attainable to a lot more consumers. The ST1 X sits at the top of Stromer’s ST1 lineup, but doesn’t give up much in terms of components or the nifty electronic functions found on their more expensive models…
All the electronic components and wiring on Stromer’s e-bikes are concealed inside their frames to create a simple, seamless appearance. Hidden inside the (obviously oversized) down tube, a 48v/618Wh battery provides power for the bike’s 500w/35Nm CYRO rear hub motor.
The ST1 X boasts a top speed of 28mph (for the USA, that is- European versions are limited as per local regulations). Regenerative braking charges the battery as you ride, allowing the Stromer to achieve a range of up to 70 miles on a charge. For an extra $500 USD, you can also opt for a stronger 814Wh battery which boosts the range to 90 miles.
The battery pack can be topped up while in the bike or removed for charging at home or work. The charger plugs into a standard wall socket.
The mid-range ST1 X still includes connectivity to the Stromer App and Omni portal functions as we’ve seen on Stromer’s pricier bikes. It also features the same touch-screen control unit built smoothly into the top tube. This unit allows you to control the bike’s settings and displays your current speed, battery life, and selected power assist level.
Stomer’s smartphone app tracks your bike’s mileage and service intervals, and allows you to configure the motor settings via your smartphone. The app also controls Stromer’s clever anti-theft function – when the bike is locked, the hub motor goes into a high-resistance mode making pedaling almost impossible. If someone still gets away with it, an internal GPS tracker should tell you whose door to send the police to.
The ST1 X’s aluminum frame is mated to an aluminum fork, which is a step down from the ST2’s carbon front end but obviously accounts for some of the price difference. The X model features a Shimano SLX 1×11 drivetrain, and Tektro Dorado disc brakes. The bike runs on 26” wheels wrapped with Schwalbe’s puncture-resistant Big Ben tires. Stromer includes their own aluminum fenders and Racktime rear carrier rack, plus the e-bike bonus of integrated front and rear lights.
Stromer’s ST1 X is available in a Comfort model with a sloped top tube (17” only) or Sport models with 17, 20 or 22” sizes available. Weights are not provided, but given that Stromer’s smaller battery comes in at 9.25lbs I’d expect this bike to be fairly heavy. The ST1 X sells for $4999 USD, and comes in orange, charcoal or white.
