We've spent day with and on the new ST5 at the Stromer HQ.
Interview with marketing experts, chief engineer, handover, installing OMNI on our phone, riding, testing, photographing and filming. The bike is in final stage. Only the "fine-tuning" of the drive modes has to be finalized. Then, the authorization for Swiss roads will follow - which will be easy; thereafter, they apply for EU approval, which will be more bureaucratic.
We focused on these points:
- Shape, style, look - in comparison with the ST2s
- Riding comfort with rigid fork and Pirelli super tires
- Key- and seamless lock / unlock (Bluetooth)
- Keyless battery eject
- acceleration (sport mode)
- hillclimb (no more boost mode)
- downhill (motorbrake)
- handling (narrow turns)
- ...
MGMT summary:
The ST5 is completely different from the other Stromer. ST2s and ST5 are not competitors, they are complement one another. Depending on your riding style, you have to choose. The appearance is completely different - so you have to choose again. If you go for longer distances, putting more value on perfect look: Take the ST5

I also would like to know what no more boost mode means and what sport mode really is

- Shape, style, look - in comparison with the ST2s
The broad stem and the massive handlebar are inline with the upper tube. The extra large Pirelli playing the key role.In a size until now only seen on MTB, they make the bike looking more massive. In comparison, the ST2s looks more like a bicycle.
The absolute clean handlebar is more conic. Therefore, it might be impossible to mount additional equipment. Unfortunately, the blue LED of the M99pro is almost covered. Drivemode and lightbuttons now on the left side, but behind the horn somewhat out of easy reach.
The rear end once more modified. Now cleaner than ever. Brake saddles in a different red than the color stripes.
Over all, the ST5 has the clearer look. More discreet in the painting, but with a clear language in size and shape. Even as the company has rear rack and suspension fork in the pipeline, think twice before mounting such devices.

- Riding comfort with rigid fork and Pirelli super tires
The main question: Why rigid fork?
The simple answer: Because it's sufficient.
The Pirelli tires in MTB size at 1.9 Bar have very good suspension capabilities. The concept is: broad rim, large tire and low pressure.
Whatever I tried, I didn't miss the carbon fork (or the FOX on my own Stromer). I always felt safe, never observed moving sidewards (due to low pressure or weak carcass of the tires) .
The Pirelli have motorcycle-like profile and running silent. Grip on dry roads is fine. I had the impression, it took longer until the rear wheel blocks whilst breaking.
I missed a real tough road (e.g. with rootage), but from my point of view, the ST5 has no need for a suspension fork.
I believe I am not in your age group or riding type . I will not buy any bike w/o a suspension fork and I have to have a rack until they make battery packs that can tack me over a 100-125 miles on top assist or a space on the frame to take a spare w/me. I have my ST2 and go out 1 blue and 2 gold and still run out of juice on weekends. My Ortleib bags rip about once every year or so and must be replaced due to the batteries. My Stromer racks need to be "re-formed" from the weight of the batteries too. I put high mileage on these bikes they need to be less maintenance also, 8 K per year avg

Thank you for bringing this critical point to the debate.
I'm writer and admin of stromerforum.ch The forum and all its writers and admins are completely independent from myStromer AG. We pay all charges from our own pocket.
You may have realized, that my report on the ST5 comes (to?) late. All others (media, dealers, affiliates) already had made their rides. We from stromerforum.ch hat the intention, doing more than a few rounds on a parking lot. We want so spend km & km, hours & hours with the ST5. Therefore, I asked my employer for one day vacation - and asked myStromer AG for a visit and extended test day.
My writing is short, I try to keep neutral. An example: "Brake saddles in a different red than the color stripes." My personal opinion was, this disturbs my eyes. Like two accent colors in a high level wardrobe, which should be the same, but aren't. I discussed with my colleague, who accompanied me. For him, this was no problem.
It's up to the reader, to deal with my statement - and I hope, my explanation will help to classify.

Of course a "rigid" fork can have a lot of compliance depending on how it is designed. I've ridden my racing bikes at very high speeds over poor pavement. Granted, a road bike weighs a lot less than a typical e-bike. Regardless, if you're riding in an urban environment and you know the route well, you would also know where and when not to ride at 28 mph...its just as dangerous to ride recklessly.
An important point “know the road well”. My 1st fall on my 1 moth old ST2 was 2man hol cover pot holes 8 feet from each other. The road was repacked with inches of new asphalt but the man holes were not raised. I believe they were lower than the pavement before the redo. I found the first , almost lost my balance , started recovering but the 2nd took me down. Quit riding this bike til I got a front suspension in a couple weeks weeks, rode my wife’s st1 with suspension waiting
One of the pot holes has been repaired the other not. I wrote the DOT over this. I believe i would not have fallen with suspension. Less than a mile from home

Fortunately there will be an optional front suspension fork. I also think it should come as standard but get by on my ST2s without it and probably will never get one for my bike.
I do appreciate bluecats passion for this bike and am very happy he put up all this extra info about the ST5.
I also want to thank bluecat, I am even more critical of this bike as I plan to purchase one for retirement, not just voicing an outsiders opinion. We are about to take ownership of my wife’s ST2s. We have only owned Stromer through good and bad times. 2011 I think

For the first time ever on a Stromer, the ST5 has Bluetooth functionality. Until now, you have three possibilities to secure youre Stromer when you leave it:
- Mount a tough lock; e.g. ABUS Bordo
- Lock the Stromer at the display and unlock with typing in your PIN code.
- Lock and unlock using the OMNI app - as far as you have sufficient internet connection
To set up this functionality, you have to pair ST5 and mobile device a first time (Code protected). From now on, you can use it - or disable, if e.g. your phone is running at low battery and you forgot the charging calbe at home (therefore you can not plug in at the ST5).
We had the Bluetooth on the whole day and the lock / unlock works all the time. Compared with the OMNI, which is strongly dependent from the quality of the internet connection to the Stromer and to the OMNI, a big step forward. But we observed more battery consumption on our mobile device.
The Video shows the lock / unlock process in real time.

Tough question; Bluetooth is able to deal with multiple connections (using stacks), but does your phone support these?

- Acceleration (in sport mode)
Starting at the traffic light and leave all others behind. The key discipline of the ST2s. Now the ST5, 48NM but bigger wheels. Will the back view still be all what other bikers will see the ST5?
A ST5 and a ST2s were ready for competition. But we had to drop the sprint. The whole day, a strong wind was blowing, sometimes with some extra blasts. Under headwind, 45 km/h could not reached. Not the fastest would have won, more likely the one with wind-luck.
With the 1.8kg camera in hand it was easy to accelerate to more than 45km/h. Without camera - with both hands on the handlebar and always firmly in the saddle - it was much faster and it was also reached more than 50km / h (which was probably on the tail wind).
An important finding is that the dreaded rubber wall was not noticeable. About 45km/h runs the ST5 clean, the factory calls 48km/h as a measure of things. But also did not come up the annoying brake, so that downhill - on safe route of course - not longer was limited to 48½km/h
This pleasing new setup shall be rolled out on all 2018 models.
Not only the sprint counts in the category acceleration, also the kick, when finally the "snail speed zone" finished. Here, power and performance are equally evident. Even with a slight incline the ST5 pulls off - assuming own contribution.
It remains the "perceived" assessment: Due to the larger wheels and the geometry of the ST5 is the smoother vehicle compared to the ST2s. So it is seemingly sluggish than the ST2s - but as the work assures, just seemingly.
The control panel on the handlebar with the gear indicator has disappeared. Thus, the beep, which announced the end of the available translations, disappeared. The speed steps [1] to [3] and are set on the control button. The respective setting can be read on the display on the top tube.
The classification at the time of the test is not final. We put the [2] on the snow with OMNI - and then hardly noticed a difference between [1] and [2]. Similar, came into its own, which may also be due to the wind.
This VIDEO shows a leisurely start with one hand on the handlebars and about 1.8kg heavy camera in the other hand.

In order to unleash the full power of the ST5, it is necessary to adapt the shifting. The Shimano Di2 is extremely fast and precise, even self-adjusting. On the other hand, it is programmed for racing bikes, where fast downshifts on uphill gradients are required.
For the ST2s and ST5, however, the rapid upshift is important. For this purpose, the assignment of the buttons must be swapped so that the "up" button is closer to the thumb. This is possible with the Shimano E Tube Project.
The connection (Shimano part number EW-RS910) is now housed above the bottom bracket. There you can also check the charge status of the Di2 battery. The cigar-shaped battery is rattlingproof housed in the top tube and very productive. Reloading is via plug, programming is also possible via Bluetooth.
My understanding of fast acceleration:
No, not this. I mean fast acceleration on your daily commute. Always keep in the saddle, just shifting gears superfast whilst pedaling normally. Here's my recipe:
- Set the saddle in proper height
- Change the settings as described above
- Approach a red traffic light.
- Shift down (like you had no motor)
- Wait for green light. Watch your competitors. Give them a smile.
- Start pedaling as usual
- Shift gear up faster than ever before
- When reached largest gear, look back...
