    New cranks for bafang Ultra

    These 20mm shorter cranks work better than the oem 170mm cranks. Less hits to the ground.


    Perfect for my cobra pro and biktrix ultra fs

    Great set but...

    Had to purchase a replacement set because one got bent due to a mishap.
    Great length and less prone to pedal strikes they say.
    However, Biktrix support (as good and responsive as they are) needs to NOT send a universal style puller to change these out.
    It absolutely will not work on these arms and the Bafang ISIS setup!
    Please stock and sell -OR- recommend the Park Tool CWP-7, it works like a charm! It has 2 interchangeable tips that go on the extruder bolt,
    whereas the universal tip is much too small and doesn't press up against anything, as the spline is hollow. And the video link to lay the bike on it's side to help the universal do the job is unprofessional and an unacceptable way to do the job.
    Biktrix universal on the left, Park Tool CWP-7 on the right. Happy e-Biking!

    Cranks are great!

    Shorter cranks are great for avoiding hits. But the q-factor is a bit wider and takes a bit to get used to. Otherwise very high quality and would recommend!

    This does fit my Himiway Cobra ebike

    I really like these cranks! No pedal strike and less ghost peddling for my Bafang Ultra ebike.

    Great product, but pricey shipping, even in Canada

    Miranda 150 mm cranks

    Just what you need to keep your pedals and cranks from striking. These will allow you to pedal through turns as well. The short cranks make such a difference it will make you wonder why they don’t come stock on the bike?
    This is the only upgrade you “NEED” to make.
    I also swapped my handlebars for a 60mm rise bar. I ordered the large frame and am only 5’10”so my hands would start to go numb after a few minutes. This seemed to solve my problem. It’s nice not to have to lift your legs up as high to make a complete pedal rotation.
