Merry Christmas everyone!
I’ve been eager to build eMTB for a while, I must say “thank you” for the great build threads on the forum that makes this build so much easier. The hardest part is just waiting for the packages to arrive this time around.
This build is going to be very quick and straightforward, nothing new so I won’t go into the details, it’ll be just picture time!
Please let me know if I am missing anything!
I’ve got the boards while ago, seems little heavier than I thought, but it’s very nice and sturdy and I like the flex.
The first thing that comes to my mind is getting the belt tension right without skipping teeth, I wasn’t comfortable tightening M4 screws not to slip on the motors from my previous design.
So, now I am using M6 screws to get hold of 15mm aluminum for the truck and 8mm for the motor.
I used Fusion 360 for the sketch.
Man, how are you guys able to get to these nuts? this is the hardest thing so far, I was hoping a tool comes with the package.
Finally, I found this in my tool box.
For the 72t wheel pulleys, I got it from http://www.beltingonline.com/72-tooth-htd5-pulley-72-5m-7789 and cut the middle out. It saves tons of time milling, It’s about $30 plus shipping for each, not cheap but it’s top-notch.
Test fittings… Honestly, I can’t stand the shiny stickers on the motors, great motor(149kv) though.
M6 grub screws.
adding the idlers, this is just temporary, it will be replaced with bigger ones.
I have built this one while back, I won’t go into details about the infusion process since it has been covered in my other threads.
Resin applied before the molding process.
Don’t have a picture of the mold as of now.
Polished. It’s 23 inches long, I am planning to use it for a shorter board as well.
