Quality parts, lightning fast shipping! What more can you ask for! These arms were a great upgrade for my Bafang m610 motor eBike!
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!
I really like these cranks! No pedal strike and less ghost peddling for my Bafang Ultra ebike.
These shorter crank arms for my BAFANG 620 motor arm perfect. No more pedal strikes. I can tell that the push force in the pedal is less, but I think the savings $ on pedals will pay off. Plus with a sprocket and cassette change in the gearing these new cranks are just right.
I ordered new cranks and peddles for my Juggernaut FS Ultra. I ordered directly from the website. The new cranks appear to be about 1/2” shorter than the the ones i am replacing. Biktrix has been very good about everything i have ordered, I don’t know what went wrong here.
These 20mm shorter cranks work better than the oem 170mm cranks. Less hits to the ground.
Excellent quality but way to wide offset,bought another brand with 18mm offset not 35mm, would of never ordered if I knew that.
Perfect for my cobra pro and biktrix ultra fs
Miranda ISIS Crank Arms Set 150mm Q35
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!
fast del
Great product, but pricey shipping, even in Canada
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.
Can’t get pedals to screw on…

Hi John, these are world class cranks made in Portugal by Miranda. Are you sure you have the correct pedals on the correct side? Here is a video on how to install them. Note that one of the pedals is reverse threaded and they are not swappable between sides. https://youtu.be/biKfxOlOlw4
Great, I searched and searched they were the only ones with it in stock, super fast shipping at a good price.
Will buy from again.
Pedal strikes were getting very dangerous at the trail centre. This fixed it.My buddy ordered some for his FS Pro after seeing mine work.
