VARSTROM VSM01 Torque Mid Motor VARSTROM launched a new mid-drive motor kit in 2026, featuring a motor with a torque sensor. Currently, it comes with a fixed gauge, and you only need to purchase a suitable battery or use your own to complete the conversion of your bicycle. VSM01 offers 750W rated power, and 130N.m max torque. The top speed for the bike converted by VSM01 will be above 40km/h Feels More Like You Are Riding The VSM01 features a built-in high-precision torque sensor. Compared to traditional cadence sensors, the torque sensor accurately reflects the rider's pedaling sensation, ensuring the motor only operates when you are actually pedaling. Compared to cadence sensor systems, torque sensor systems can increase the single mileage by 20%. Support 36V or 48V Battery The system will support 36V (550W) or 48V (750W) battery (rated power will decrease by 25%). This feature reduces the purchase cost for customers who have their own 36V batteries. No Error 08 Anymore There are hall sensors in mid motor, and if one of the hall sensors damage, the system will be stopped by the error08. However, VSM01 will automatically adjust to allow the motor to work normally if one hall sensor fails. If multiple hall sensors fail, the system will switch to hall-less mode (in which case the system will vibrate at the beginning). However, when the speed increases to 15km/h, the system can still work normally. Customers can ride the bicycle home and have it repaired. Brake System Options Varstrom offers 2 brake system power - off options for customers. If you're using a hydraulic brake system, Varstrom recommends you choose Hydraulic Brake Sensors.
