Stromer (ST1x) - How to activate the service menu - Test run with battery capacity

[@davidebianculli9192]

Does it work also with new Stromer bikes (ST7?)

[@JanWillemWisselink]

@@davidebianculli9192 it should work with an Omni-C (color screen) as well. Use right brake to access the service menu. If you have used it ones; you have to reboot to access it again if you have left the menu.

@@JanWillemWisselink I have the ST7 but it asks me a service PIN code when I click on Service. On ST2 I had before it was without pin.

hi, thank you for the tips. Is there any solution to get more power assistance (>45km/h) ? I put all settings in full.

[@JanWillemWisselink]

Your welcome! I haven't seen any Stromer ST1x hacks until now which allow you to alter the maximum speed limit. My ST1x is capped at 48.3km/hr. Above this I notice support it going down until the speed is back at/under 48.3km/hr. If you have all settings at full (Sensors & Motor Tuning in Omni App) and support is lacking, they only thing I can think of is calibration of the torque sensor. This needs to be done in de Omni on the bike itself. But judging from your question, you're looking for a hack on topspeed ;)

@@JanWillemWisselinkThank you. I got this bike for 2 years and use it every day (30km return included). The negative point is that bike consums many chains. I have to change the chain every 1000km (worn out at 0.75 with chain tool check) and the cassette every 3 chains. I changed the 11 speeds cassette into a 8 speeds cassette it is enought for my usage and it is a cheaper component. The last change I did : I change the cassette 8 speeds 11 tooths (11T) for small ring into a cassette 8 speeds 12 tooths because the first ring 11T worn out quickly. The consequence of this change is it is harder to reach 45km/h speed.

@@frdonn Woo... That is a fast burn rate for your chain/cassette. I would say; abnormal even. My cycle to work distance is 58km. Therefore 116km per day. I had driven around 10000km when I first changed my cassette and chain. Trick is to let the engine accelerate you and the bike; because during the acceleration you will excert the most forces on chain/sprockets. When you reach cruising speed, you can cycle along with steady force... But this accounts for the flat Netherlands where I live; do you live in a hilly / mountain area? I have changed my cassette to into a SH 10V ULTEGRA 6700 11-23. So it still has the 11T but also the very much missed 12T. Because the 11T is a bit too heavy and the 13T too light for flat roads and cruising speed. But I agree with you that it is harder to reach topspeed, when you are in 'lower' gear. Next to this I change between two chains every end of the week (so every 240 to 480km depending on how often I cycle to work... which depends on the weather) Stromer has probably matched the average torque/cadans of each gear to the amount of support. I think the system can only be tricked by changing the calibration of torque sensor; shifting the voltage range. If I am correct; The 11T would give a higher average torque over a cadans and thus a higher voltage, in comparison to a 12T or higher sprocket. So the trick is to reach an average voltage output of a 11T when you are on a 12T (or higher). Maybe (just thinking out loud.. because I haven't tried this) it might work to calibrate the sensor with some weigth / force on the pedals. This would shift the minimum voltage to a higher level... but the question is; does is shift the maximum voltage...

[@frdonn]

@@JanWillemWisselink thank you for your lesson learn about your bike. Well, I hesitate to touch the voltage because it can break the engine. A new ST1x engine cost 1200€. You are right, on 11T you get the max power but tooth are bit weak. My daily trip is a bit hilly but not like a montain. When I ask to bike dealers about chain/cassette usage, they reply me it is normal.The best chain that I found is a SRAM special for eMTB and I could use it for 2000km before change it. Many thank and enjoy that good bike :) Cheers!

[@JanWillemWisselink]

@@frdonn Oh; with the voltage, I meant the voltage coming from the torque sensor. I not saying you should increase voltage to your engine!! That's a very bad idea (even if you could..)

Kom je uit Nederland? Ik heb zelf nieuwe stromer ST1 gekocht. Zou ik graag contact met u op als het mogelijk is? Dank je wel

[@JanWillemWisselink]

Jazeker! Kom maar door met die vragen. En anders kan je ook terecht op het Stromer-Forum (speedpedelecreview.com); daar heb je veel mensen (ik zit er ook op) wie je verder kunnen helpen
