How to choose the transmission with a mid drive MTB motor?<\/h2>\n<\/div>\n
<\/div>\n<\/div>
<\/div><\/div><\/div><\/div><\/div><\/div>

With the LIFT MTB electric crankset motor kit, we use a single chainring at the front, usually with 32 teeth, which is the most suitable assembly for most cases.<\/p>\n

In this article we will see how to properly choose a transmission <\/strong>for electric bike<\/strong> according to your practice & bikes.<\/p>\n<\/div><\/div><\/div>

Single, double or triple plate transmission?<\/h3>\n<\/div><\/div><\/div><\/div><\/div>
<\/div><\/div>

The use of a double or triple tray with a LIFT-MTB<\/strong> system would not really be of interest. The extra power available from theelectric motor<\/strong><\/a> will allow you to compensate largely.<\/p>\n

You won’t need the small gears anymore, so you gain in weight and ease of use.<\/p>\n

If you have a recent bike with a single chainring and a high amplitude cassette (e.g. 11\/40, 11\/42 or 10\/50) such as 1×10 speed, 1×11 speed and 1×12 speed, which are coupled with the LIFT-MTB<\/strong> system, are ideal.<\/p>\n

That’s why most of the current bikes are 90% single chainring<\/p>\n

(Our narrow wide chainrings are compatible with 8 \/ 9 \/10 \/11 \/12 speeds).<\/p>\n<\/div><\/div><\/div>

Note that if you have a small cassette under 11\/34 or 11\/36, adding in a second time a cassette with bigger rear sprocket steps like 11\/42 available on our store, can be a good thing if you really want to climb very steep.<\/p>\n<\/div><\/div><\/div>

<\/div><\/div><\/div><\/div>

We propose on our store 8, 9 or 10 speed cassettes <\/strong> with a more “modern” stage with larger sprockets, which will allow a modification in single plate (1X) thanks to a very consequent stage.<\/p>\n

It’s a good way to upgrade your 8v, 9v or 10v transmission at a lower cost (around 59euro) and have even more torque.<\/p>\n

The advantage of our solution is that you keep the same derailleur, the same chain and the same shifter… and you will have the equivalent of a “modern” transmission at a lower cost!<\/p>\n

Picture of a “road” type rear cassette with small sprockets (11\/23) which allows to have very precise ratios on flat roads, but which doesn’t offer a big torque to make steep climbs for electric bikes<\/strong>.<\/p>\n<\/div><\/div><\/div>

Picture of an “enduro” type rear cassette with bigger sprockets (11\/42) which allows a big amplitude between the small and the big sprockets, thus increasing the torque and making it easier to climb steep hills for electric mountain bikes<\/strong>.<\/p>\n<\/div>\n

For your information, 1 tooth more on the rear cassette sprocket is equivalent to 2.5 teeth less on the front chainring.<\/p>\n

So if you go from a transmission with an 11\/32 cassette to an 11\/42 cassette, (there are 10 more teeth on the biggest sprocket of the rear cassette).<\/p>\n

It is as if we had 25 teeth less on the front plate, the difference is enormous and the gain of torque thanks to the change of k7 is a real plus in the very steep rise!<\/p>\n<\/blockquote>\n<\/div>
