Hi Idea, great stuff, I sent you a private message .
Hi man, Great work!!!, This post was all I wanted to see… I have a scrub MTB with five bolt holes wheel hubs like the drawing below. Would it be possible for you to make me a pair of 70 or 72t pulleys? please? I would really appreciate it. Of course I would buy a complete dual motor mount set from you…
@falesias No problem, Who is a producer of these hubs?
Can you show pictures of these hubs?
What trucks do you have?
Measure this dimension
Hi man, Thought you might ask that… 57mm / 2 = 28,5mm The mtb is a SCRUB so I gess the whells are also… They are very popular in the UK

Think he needs to know your Truck type ie Spring or Skate truck…edit im guessing its spring but pictures of your truck as well will help
Hey man, I’ve just noticed you’ve recently posted a photo of what looks like an updated version of the mountain board mounts here which include an idler pulley on each mount:
Do you have a price available for these kits? I’m based on New Zealand 
@falesias 1.Price of pulleys made of aluminum: HTD5M 72t, width 28mm (25mm belt) - 45 Euro (1 psc) HTD5M 72t, width 23mm (20mm belt) - 45 Euro (1 psc) HTD5M 72t, width 18mm (15mm belt) - 35 Euro (1 psc)
2.If you want to order motor mounts, I need to know what trucks you have?
3.If this dimension is 57mm, the distance of the hole for the screw to the axis of the hub will be different than 28.5mm
@michaelcpg it’s a prototype. Not tested yet, too early for mass sales…
The price for motor mounts with a belt tensioner will be 150 Euro Kit with belts (20mm width) and pulleys 72t/15t made of aluminum - 280 Euro Shipping costs to New Zealand Shipping by post office - 50 Euro (delivery time 2-4 weeks) Shipping by courier - 75 Euro (delivery time 7-10 days)
The motor mounts is made of high quality aircraft grade 7075 aluminum 
and stainless steel, so I’m not worried about the strength of the structure, but I have to test the tensioner rollers.
The new mount has the same crossbars type as the previous version, so if someone has a previous motor mounts, he will not have to order complete motor mounts, only side panels.

Hi Ok, maybe my drawing isn’t as explicit as it should be. That’s because I did it on the laptop from my couch heheheh… (and not on the desktop’s big screen) sorry The 57mm dimension refers to the diameter of the circle containing all hole centers, and not, as it seems like, de direct distance between those 2 holes. Sorry, my bad… So, I guess if the diameter is 57mm, the radius is 28,5mm, right?

Hi, Sorry for taking so long Distance between hubs is 295mm approximately (Couldn’t get the tires out, but I think I got the measurement right)
