The belt drive is awesome. I see no issues so far. I am having issues with the rear Mavic hub that came with the bike but nothing with the belt.
The current setup (39T front, 32T rear, 125T belt) is significantly undergeared for any fast riding but plays little role when gunning down the...
Also interested to know how you travel with ebikes on planes. They are heavy, plus the bag (say 10kg) and the whole setup becomes very heavy indeed. And the battery? Do you need to remove it and put it into your hang luggage?
I was thinking about this. Based on the pictures and videos, given a different bottom suspension pivot location when compared to Voima, it appears that there might be less space for sprocket.
Perhaps you could inquire with Pole what is the absolute maximum front sprocket size that could be...
Hi, I am glad there is at least interest in this prototyping stage :)
Indeed, there is very little chain growth. I guess the roller's placement is crucial. Around time when I started prototyping with various extension arms, I visited a pretty cool Swiss brand using Gates components. Once very...
I have a question for those who are riding Voima with the standard rear shock, any shock setup guide/setting and user experience you would like to share?
Hi all,
The progress is slow at the moment and will remain so for the next month or so. On the flipside, I think I have the tensioning roller positioned fairly well.
Protos 8 and 9 are of the same basic adapter shape but with the tensioning roller positioned is a slightly different spot. I...
Potential solutions:
In both videos a full wheel travel was tested to see if (1) the belt's teeth do not touch at zero wheel travel; (2) the belt tensioner was still able to extend (squeeze the spring) at a full wheel travel; and (3) the belt was long enough at a full wheel travel...
Houston, we have a problem.
Today I have received the 122T belt. So far I have the following belts: 120T, 122T and 125T.
The problem I discovered is the chain growth:
The 120T belt is too short. Nothing to add here.
The 122T belt is slightly too long when the bike is unweighted. Yet it is too...
Re 1: Indeed, this is why I could start prototyping. I have the tensioner and a bashguard in hand. Even from the stage when I was just visualising, having it in hand made some realisations. For example, I would have wanted it to sit closer to the engine axle but there is not room.
Re 2: The...
Welcome everyone and a Happy New Year 2024!
Indeed I have been on the case to somehow buy these.
For Voima, it would not be a straight fit. An adapter would have to be made. Since I do not have access to 3D printing or a professional machine shop, I guess the process would consist of (1) CAD...
Interesting.
Is your Voima the LED or the ID model? I also wonder whether the fact of rim mounted magnet for speed sensor would make any difference.
European eMTBs are limited to even less than 20mph so the tune would be an interesting updae for my project.
