I will try this when I can but I am almost positive that I can use S mode well below %40. Are you sure it was not because of thermal limit, it is conservative and S mode dials back to 3 when it hits the limit.

Linklemming's formula is correct. You are taking the ratio in the wrong direction. In my post I have derived the formula in case you are interested. Your driver is your chainring and the cog on the wheel is driven.

Once again @AbeK summed it up perfectly there is really nothing to add to that. I also agree that FS mid drives like yours and Abek's are fantastic tourers. The problem with 30+mph is it is above 28mph so no legal bike will give full support at that point. Above 28mph ST5 has a milder...

We can easily derive the needed equations, I hope this clears things up. If Power was perfectly preserved(assuming no drivetrain losses), (Torque at the crank) x (rotational speed of the chainring) = (Torque at the wheel) x (rotational speed of the wheel). => (Torque at the crank) x...

You know, I stopped responding to some posts because I realized that the communication was too similar to what you would have with an online banking "chat bot". At some point in the conversation, you reach a point that contradicts or outside of the set of pre-implemented responses/conclusions...

Definitely get a good stand, it is hard to do the adjustment without a stand. As has been suggested you have to loosen (turn counterclockwise) the the low limit screw. It is a similar problem. At this point you may do the adjustment from the beginning. You can follow this guide, it does a good job.

Good information. These regulations explain the difference in sales numbers between regular ebikes and speed pedelecs. When I checked the numbers of ebike sales speed pedelec sales are in thousands yet regular ebike sales are in millions. It is really simple, when a company already selling in...

Unfortunately most of the time this is true. For these people 249W is underpowered 251W is a moped because bosch advertises 250w nominal. If tomorrow bosch comes with a 700W nominal motor you will see the same obsessive fans singing a different song. Not all of the owners are like these people...

Until @AbeK replies let me share my experience with my ST5. I can take it very close to 31mph on the speedo however after that you kinda hit the wall. Also your RM over-read your speed so when you see 28mph it is most likely in the 26-27mph range in the real world. If all you need is several...

Completely agree with all of these. On very hard braking rear wheel can slide. It happened to me too(a car coming on the opposite direction turned left on me), but each one of those I never lost control. That being said I think it can be prevented by getting used to the brakes and adjusting the...

You shouldn't dismiss this feature. There are some big positives. Recouping is one, braking is another. Actually regen braking downhill is amazing. Instead of generating heat and wearing out brakes it recharges my battery. Mid drives can not do it. Geared hubs can be designed do have it, grin...

So lately I had the need for bleeding brakes on my Stromer St5 which should also be similar for Stromer St3. The brakes are custom built by TRP. They are 4 piston brakes with great stopping power however since they are customized it may be a bit confusing to figure out how to bleed them...

Let me again re iterate, for emtb applications mainstream motors are great, they are built for that. In technical climbs it is not only about the amount of power, it is also how it is delivered. Also I agree that some of the Chinese motors have inflated specs. They do it because of lack of...

It is more important to establish the difference between peak and nominal power ratings. The definition of nominal is the power that can be sustained indefinitely, peak power is the maximum power that can be reached but for only a limited period of time. To keep a high speed one needs a high...

Check limit screw, seems like it is too tight.

Because bosh is serving for the speed limited European market. These motors work well for such a market and emtb. Instead of coming up with a proper high powered motor true speed pedellec motor for US market they remove speed limit and sell the same stuff at a premium. Price discrimination is a...

not planning to sell? I guess it is time for an offer you can't refuse. Joking aside, I really like x1 good components/power at a very good price. I am just a bit worried about the carbon frame, how is it holding up? Any quality issues ?

:) So true. I don't think the difference between gen 2 and 4 is drastic since it is only a couple of additional gears that are turning not the motor itself (there is already a clutch for that). The only reason why people are faster at lower assistance levels with gen 4 is because gen4...

Feeling natural has nothing to do with motor being mid or hub. It is about having a torque sensor and controller being programmed properly. Finding a good hub offering with a good torque sensor is harder, mainstream mid drives are all over the place. I have bikes with bosch Cx, yamaha pw-se...

Give waxing a try, here is my thread ebike lubes it made a big difference in chain life in my mid drives and I have tried many different lubes. Conditions and where you ride makes a big difference. Waxing in many conditions keeps the chains clean. There is also the issue of miles not being a...
