I have Bulls Vuca EVO AM 2 and the belt has fallen off twice at maximum load in uphill conditions. The gates app show the belt tension is 36 HZ, it it possible the set the belt tension?
I think Pinion has a very real chance at disrupting Mountain bike drivetrains forever. If you guys focused on a Downhill Specific drivetrain based on this belt system and tensioner, Pinion would be THE drivetrain for DH. The only obstacle right now is the shifter. Grip-Shift is NOT an option in downhill for many reasons, but if you implement electronic shifter with paddles, which now are an option for Pinion if I am not mistaken, then the whole game changes. Think about it: Downhill bikes only need 5-7 gears, which would reduce weight. They also are Gravity-driven, so drag is less of an issue, provided it is not too much. They would benefit enormously from being able to shift without pedal, or in the air. Many riders are using O-chain cranks, which purposely create lack of engagement, in order to reduce suspension interferences. In pinion bikes, this is looked upon as a bug, could be a feature. Modern high pivot suspension linkages work great with gearbox configurations, just make sure ground clearance is enough.
Also: I forgot two of the best features for DH bikes! 1. Unsprung mass off the rear wheel, would make suspension work much better, and reduce the amount of flats and smashed rims. 2. The weight of the gearbox being pretty much in an ideal position in the center of the bike, improves stability, predictability and in-air handling. No more questions, your honor!
Good point, although to be clear, the gates carbon drive literature currently says to avoid back-bending the belt "by hand." It also says to avoid forward-bending the belt by hand. Based on the obvious mechanics, I think it will inevitably shorten the life of the belt. Based on their precise use of language, I think/hope it will still meet/exceed expectations.
chain/belt tension is of course good especially on full suspension. but where is long awaited bash guards for those who own pinion AM/enduro hard tails?
It can become a nightmare if you have a flat and don't have the tools. I just tested a (heavy) commuting bike with that system and it's a pain in the bottom to remove the wheel compared to a derailleur and chain.
I ride a recumbent trike HP Velotechnic Scorpion FS 26 with a C 1.12 pinion drive. Is it possible to use a belt versus a chain? Maybe this is a HP question but thought I would start with you. Thanks in advance for your response.

Gates mentions to avoid back-bending the belt. With that in mind, does this tensioner reduce the life of the belt? What is the pulley diametre?

Please refer this question direclty to HP. For a belt the bicycle frame must be able to be opened, to put the belt in place.
