Excellent idea. What about adding some resistance to the rear rollers though? Would that make for a lower gear/more natural riding experience, I wonder? Also, if the rollers had a rougher surface, how might that improve control?
I found that adding resistance made me roll of the rollers rather than spinning them. That could be solved by either adding a bungee cord to keep the bike in place or adding the resistance directly to the bike wheels/frame. Roughing the roller surface might help a bit, though the wheels never seemed to slip
There is a tiny bit of vibration, but I don't notice it. It's smoother than most roads where I live. If you make the roller caps like I did, then they'll be very close to perfectly concentric to the bearing
Thanks! It's actually very little resistance unfortunately. If it had much more then one would move forward rather than spinning the rollers. I think that one could add more resistance if the back rollers were further apart, but that might affect the handling of the bike
@@janionmakes I am building my own rollers and i made rear rollers axles 30 cm apart from each other and they are both on same height. Im still experimenting so i might change that but i did not have any issue with my bike rolling off the back or front at all. I had to put front roller 27 mm lower than rear ones or it would rise front of the bike up too much. It might be bad set of bearings but i have good deal of resistance on my rollers for some reason. Anyway your project is good motivation
@@tskedition mine are only 21cm sorry, so 30cm sounds good. I would have put mine further apart of I want trying to fit 2 different bikes. The type of belt you use might also affect the resistance
The screams at the end were great!! 😄 Nicely built! 👍🏻
Thanks :) That was genuine terror
This is so good, can't wait to see more projects!
Thanks, I'm looking forward to attempting some more ambitious projects soon :)
Great build and nice video. Well done!
Thanks very much :)
Haha best video yet!
Thanks!
Such a good idea, my brother would love a set of these!
Thanks, they'll be worth their weight in gold come winter
Nice work! When does Si get his Dogmill?
Haha soon... I won't be any more specific than that!

Another thing i meant to ask how perfect do your rollers spin is there any noticeable vibration when riding fast?

Seems like nice design and well built. How much resistance do you feel riding on those is it comparable to slight uphill?
