Hey guys,
I currently have a BBSHD on my mountain bike. Is there anyone that can compare the BBSHD to the X1 Pro? Has anyone done a comparison of the pro's cons of each system? Also how does this system do off road. I only ride off road just on the weekends on Single Track All Mountain Trail riding. I'm looking to do a new build but want to do something a little different.
Don't know if you have built a CYC yet but I started out with a cyclone kit that turned out to be a completely custom install, then fitted tsdz2 to numerous bikes with various osf software versions and displays, then built a BBSHD fatbike with "Karls" settings, then an x1 pro gen 2.
I got fed up with bad chainlines on the kit bikes and numerous workarounds and now have a perfect chainline on my cyc using a modern boost chainline frame. I have a 38t chainring version with a 11-46 rear and I can spin out but don't care about top speed as I use this as a MTB. I have a motorcycle that breaks all speed limits, goes 3 hours on one charge and charges in minutes due to unleaded, but I can't take it on local trails, even with scottish access rights, and can't carry it on sections that I can't ride.
The BBSHD definitely had more power than the tsdz2 but the PAS response was a bit on and off compared to the tsdz2 and made technical singletrack more of a motocross experience rather than a trials section. Started riding fatbike on throttle more of the time. I had expected more power from the BBSHD over the tsdz2 but put the marginal improvement down to my 48v unknown cells battery. with 30A bms. Responsiveness to pedal input is a definite improvement over tsdz2, better quality torque sensor, better quality controller and pawl freewheel rather than sprag clutch probably all contribute.
Still building my custom battery for my X1 pro so I used my fatbike battery and I have removed the throttle as the PAS is natural and responsive and it's my bicycle not my motorbike. X1 pro set to 1250w at the moment due to battery and performance seems better than the BBSHD at 28A and seems to consume less power. Both are faster than my brother who is on a tsdz2 osf. Looking forward to a bit more power when I build my 52V 60A battery but suspect the only times I will consider using it are when I spot someone slogging uphill on a £6k factory ebike ahead of me.
BBSHD definitely quieter than any of the other setups, tsdz2 ridden with both plastic and brass gears I would rate BBSHD as 1, tsdz2 as 2 with plastic, tsdz2 as 3 with brass and CYC x1 pro with brass as 4. My old cyclone had steel gears and was more of an angry wasp 5.
Considered the cost of a CYC as an expensive outlay, then thought about BBSHD and upgrading chainring and controller and thought similar money is involved in both and the BBSHD will never have a torque sensor. The tsdz2 is a great budget option but some of the tolerances are dubious but it's easy and cheap to fix when you break it.
I have tried fitting tsdz2 and BBSHD to some mtb frames and found that clearing the chainstays with the motor is either impossible or exaggerates the bad chainline to the extent that splitting cassettes only gives 3 useable gears.
All of them are good in their own way but I would definitely walk past the others to get on my x1 pro at the moment.
