Stromer-ST2-S-title-shot

If you’re really interested in technology, you’re probably stoked that e-bikes are bringing some cool new ideas to the marketplace. Even if you’re adamantly against assisted pedalling, it’s pretty nifty to see how companies like Stromer are incorporating electronic features into modern bicycles. Without electronic components it would be tough to make a bike that allows you to ride longer distances, let alone one that tracks your ride stats, monitors service intervals, or hosts anti-theft features.

Swiss e-bike manufacturer Stromer seems quite pleased with itself to announce the availability in the US of their new top of the line ST2 S e-bike. The S model has seen a few upgrades over the base ST2, including XTR Di2 wireless electronic shifting, a 20% larger battery with a range up to 110 miles, and an integrated 1600 lumen Supernova headlight.

But all of this technical innovation certainly does not come cheap, and considering the bike’s overall heft the and lack of a carbon frame, it seems the electronics are largely what you’re paying for…

The newest Stromer is powered by a 48 volt, 500 watt SYNO rear hub motor that provides 35 Nm of torque. The ST2 S is billed as a pedal-assist bike, but in ‘move’ mode it will help you achieve speeds up to 28mph at three different power levels… However, there is also a ‘boost’ mode which allows you to cruise at 12mph without even pedalling. The 983 watt-hour lithium-ion battery sits in the down tube and provides an impressive range of up to 110 miles per charge, partly by using regenerative braking out back to juice itself up as you come to a stop.

The Stromer’s frame is made from 6061 Aluminum, and it comes paired with a Stromer ST2 carbon fork. Despite using these lightweight materials, the e-bike’s 11 lbs of battery, hub motor, and electronics bring the bike’s total weight to a portly 57.5 lbs. Don’t worry, you aren’t likely to catch this one on your trails. The battery pack takes five hours to charge, and can be plugged in while still in the bike or removed and placed in its own charger unit. The battery is warrantied for 1000 charge cycles.

One of Stromer’s unique innovations is their cloud-based platform called Omni. Using the Stromer Mobile App riders can connect their bike to a smartphone (Android or iOS) and control various features or check up on their bike’s stats. On the bike itself, a touch-screen interface on the top tube allows you to control the electronic functions and access ride data collected by an on-board GPS tracker.

For dealers, the web-based Stromer Portal site keeps track of each bike, allowing them to analyze and configure each customer’s ST2 S, track services and maintenance, and access ride data like mileage, etc. The portal also connects bike shops to technical support from Big Brother Stromer’s staff.

One cool feature of the ST2 S is its anti-theft mode. If the bike is disturbed, it causes the lights to flash but more importantly puts the hub motor into theft mode, which makes it nearly impossible to pedal. If the bike still gets stolen, it can be located using the GPS.

Component wise, a Shimano XTR Di2 group wirelessly shifts through the bike’s 1×11 drivetrain. The ST2 S rides on a 26” DT Swiss wheelset with Continental Top Contact II tires, and Magura’s MT5 hydraulic disc brakes bring it to a stop. The S model also comes with matching alloy fenders.

In addition to the built-in daytime running light on the head tube, a handlebar-mounted 1600 lumen Supernova M99 Pro headlight offers plenty of illumination. There’s also a USB charge port for your mobile devices, and an LED brake light on the rear fender.

Stromer’s ST2 S frames are available in 17”, 20” or 22” sizes, and come in grey only. The ST2 S is available at select retailers for $9500 USD. Oh, and you might want to check your local e-bike regulations – in tiny text at the bottom of Stromer’s website you’ll find this disclaimer:

*May require insurance and a license plate, depending on country.

UPDATE: Stromer recently decided to put the ST2 S to the test by having two riders attempt the first stage of the Amgen Tour of California on a single battery charge. Spoiler alert- both riders did finish the 106 mile long course with juice to spare, but you can check it out in the short video below.

    • Should be called ebike rumor! I quit this site for good and won’t return! The end is near! The golden days of cycling ended in 1993! Should just buy a gas machine instead!

  1. Man in a suit, with a bike with exposed chain. Marketing pictures…
    Give it an IGH, crank motor, and chain case or belt drive, and we’re talking practical transport cycling. But the electronic integration is good stuff, we’ll see more of this.

  2. I’m liking the move towards electronic integration, but the bike…. Seriously, at some point you’ve just got to say ‘screw it’ and get a Vespa. This bike (and marketing) is long past that point.

  3. Looks legit!

    My fav thing about a ebike is no matter how tired you are training you can still jump on your bike vs car and go run errands etc.

    Ive got 2 ebikes. Specialized Turbo S and a Bafang kit on a Giant Toughroad. Great for motor pacing as well. No fumes to breath in and your gf can drop you anytime she wants!

  4. for $9.5k you could buy and operate a decent used car for several years. Only tech bros of Boulder and S.F. will buy these

  5. 9500 LOL! I could get 2 Vespas for that. For that kind of cash, you may as well go gas and save half your money.

    • haha exactly, if you stay in endurance zone and have food and water you can pretty much go as long as you can mentally stand it.

  6. “Without electronic components it would be tough to make a bike that allows you to ride longer distances,” What does this even mean? People rides hundreds of miles all the time on bikes with no electronics. If anything, e-bikes are short distance machines.

  7. XTR Di2 is not wireless it has wireless setup functionality but it still uses E tube wires to connect everything together.

  8. Looks like a great commuter. I’m all about E-mopeds for commuting, but considering the price you’re WAY better off just buying a gas moped or a proper motorcycle. I had a little 250 dual sport for commuting that I paid 1.8k for. It delivered 80mpg and would do 85mph. Yes a E-moped would be greener but a little 250 commuter bike uses very little gas and when you factor in the carbon footprint of buying a new E-moped vs an old 250 the net result is probably a wash. When I can buy a E-moped for as cheap as a used motorcycle I’m all about it. Until than, I would buy a gasser and spend the saved cash on mountain bikes.

  9. Hey guys I dont understand the negative aspect on that e bike.it has by far no relation to a vespa or motorbike. Its a pedal assist bike and you still have to pedal every mile and you can choose how much assist you want or need. In my opinion this bike is designed not to replace your bike. Its to replace your car. How many hours do we waist in traffic jams or searching parking lots?

  10. All you E-bike haters need to get over your purest bias. I have ridden the ST2. It gets off the line faster than a Car. It goes almost 100 miles on a single charge. This bike is so much fun!! I went up a pretty steep hill at 28 MPH!!! If you haven’t ridden it, you don’t know what you are talking about. Go Troll a yahoo article and quit hating on something just because its different. You have to pedal it, no throttle. You are just rewarded more for the effort you put in.
