The highly anticipated Stromer ST2 was on display at Interbike 2014 to tease us for it’s 2015 arrival in the US.
The ST2 is a very high tech electric bike with smartphone integration and GSM wireless connectivity using it’s OMNI system.
In addition to being on the cutting edge of tech, the ST2 features a HUGE lithium battery with 814 watt hours of capacity. Most bikes have 360 or 400 watt hours.
Stromer has also updated their direct drive motor with features like: 500 watts, 35 Nm of torque, a freehub, and thru axle.
The ST2 will be available in March of 2015 for $6,990 (USD).
Enjoy this video that highlights the new high tech Stromer ST2:
And here are some detailed pictures of the ST2 from the show:
This ST2 comes in two sizes (20″ & 17″) in addition to a 17″ step thru style frame. The colors offered are white or black.
The ST2 has 2 front lights to see and be seen at night. There is a USB port for charging your smartphone in the headtube light (lower).
The display is located on the top tube near the stem. You can adjust a number of setting here. The smartphone app provides more adjustments options.
The ST2 is very connected through it’s OMNI system!
The smartphone app allows you to customize the ST2 performance settings.
Stromer made a splash in the e-bike market by integrating the battery in the side of the downtube of the frame. That design element continues in the ST2.
The battery door opens to the side and the battery can be pulled out.
The big upgrade on the ST2 is the massive lithium battery. At 814 watt hours it is more than double the typical 360 or 400 watt hour e-bike battery pack. That means seriously long range!
The SYNO Drive direct drive rear hub motor has 500 watts of power and 35 Nm of torque. Also note the disc brake and thru axle. The thru axle provides for a solid connection to the frame. The motor powers the ST2 up to 28 mph. It is a torque sensor pedal assist bike (no throttle).

ST2 sounds great , and questions:
You say it has about twice battery capacity of a 360-400 Ahr bike (which typically have ranges of about 20 miles ..) .. then you say in video that range is in the order of about 90 miles … Can you clarify?
And has Strom sorted out the USA cellphone issues?
When it’s stated that Omni net access is not an extra charge, for how long does that situation last?
and: is the front fork very similar to the problematic ST1 with it’s fork issues? (i know you’ve discussed this point to me privately, to my satisfaction, but I thought it should be addressed here, to ST’s advantage ;).
And:
What is the price a a 2nd battery?
And are the tires/rims 700C ?
And what is the warranty period/terms? Are your USA dealers fully able now to service/maintain?
(My dealer would be a place near Hartford, Connecticut, USA)
Also, can you tell us why you chose to have a rear-wheel motor? I’ve been very happy with my two high-end front-drive bikes and am not sure what to expect with rear-drive..
And:
Are the Schwalb tires their top-of-the-line, performance wise?? I notice Strom change to a new Schwalb tire design ..
I’ve tried to make this comment maximally useful to many of your readers .. so please do forgive if I’ve addressed issues that have been noted in the past ..
Thanks much!!

Hi Jon,
My name is Brent Meyers and I am the National Sales Manager for Stromer US. I’ll attempt to answer the majority of your questions now:
1. You say it has about twice battery capacity of a 360-400 Ahr bike (which typically have ranges of about 20 miles ..) .. then you say in video that range is in the order of about 90 miles … Can you clarify? The ST2 has a 814 WH (almost 18 AH) 48V battery. You have to factor in the difference in WH compared to 360-400 and the fact that the battery is now 48V (efficiency of the new Synodrive motor is also a factor). The 90 mile range estimate is based on riding in eco mode and of course depends on rider weight and terrain. Using the bike in normal or high power mode will decrease range; however, you’ll still get drastically more range than any competitor bike that has 360-520 WH battery (36V).
And has Stromer sorted out the USA cellphone issues? Not sure what issue you are referring to. The first time a working/production non prototype ST2 was actually in the US was at Interbike this year. The GSM network on the ST2 was working very well, as we demonstrated to dealer and press.
When it’s stated that Omni net access is not an extra charge, for how long does that situation last? For life.
and: is the front fork very similar to the problematic ST1 with it’s fork issues? (i know you’ve discussed this point to me privately, to my satisfaction, but I thought it should be addressed here, to ST’s advantage ;). Thanks for bringing this up. The original issue with the ST1 fork was actually very limited. There were minimal bikes affected in the US. The problem has been corrected for months and there are no more issues with forks. The ST2 forks are safe and adhere to our strict manufacturing standards.
And:
What is the price a a 2nd battery? Still working on it. Will have something shortly.
And are the tires/rims 700C ? No. 26×2.5
And what is the warranty period/terms? Are your USA dealers fully able now to service/maintain?
(My dealer would be a place near Hartford, Connecticut, USA)
You can find all warranty information in our manual online. All US authorized dealers are fully capable of working on Stromer’s. The ST2 will be even more easy to service, as it has onboard diagnostics and all software updates are now wireless.
Also, can you tell us why you chose to have a rear-wheel motor? I’ve been very happy with my two high-end front-drive bikes and am not sure what to expect with rear-drive.. We still believe that the rear brushless hub motors are the best for the electric bicycle application (torque, maintenance, quiet, etc). The ST2 uses our new Synodrive motor that drastically increases torque, while weighing less.
And:
Are the Schwalb tires their top-of-the-line, performance wise?? I notice Strom change to a new Schwalb tire design ..
The tires have been very well received and reviewed. They add another level of comfort and are ascetically pleasing.
Thanks!
My only concern with the stromer is what if something breaks down? Who do you get to fix it? Those electronics look very complex. I don’t think you can fix it yourself.
