March 19, 20224 yr Hi all, I'm new to the site and I'm wondering if there is any way of increasing the torque of a 250w mid drive motor so it can pull up hills better? Cheers
March 19, 20224 yr Author what motor is it ? I haven't bought one yet but it's going to be a 250w mid drive
March 19, 20224 yr under 15mph a motor can pull way more wattage than 250w more like 800w-1000w when climbing steep hills. my old bosch performance motor with 60nm of torque was good enough for everything i went up. https://www.youtube.com/watch?v=t3qDZxxzU8k:34 tho if you want to change power settings ect then baffang is the only option as bosch shimano Yamaha ect have locked software you can add a dongle to remove the speed limit but thats about it and wont give you any more power. https://www.cloudsto.com/forum/kirbebike-vapour/kirbebike-vapour-full-suspension-emtb-detail.html

Thanks for the info. I was also thinking about how there is no law in the UK for putting two 250w motors on a bike, as far as i know it only states that you can not have a motor above 250w on your bike and can not go above 15.5 mph with pedal assist.

March 19, 20224 yr my bike with a dongle can do 35mph on the flat if i spin the cranks at 120rpm but is geared for this speed. if i want better climbing then i fit a smaller sprocket on the front so would go from 21t to 18t or run dual sprockets. tho you cant do this with the new motors but you can fit a smaller chain ring to gear the bike how you like it.

Wow very cool, it's a bit out of my abilities at the minute so I may have to ask you some advice on this at a later date. Thank you for the advice.
