The Single Speed Lightning Bolt shares the same geometry with the other Bolts, but opposed to having vertical or thru axle dropouts it has rear facing horizontal dropouts. It also has 120mm rear spacing to accommodate your typical fixed/ flip flop hub. It is still designed around a 650b wheel like the other two, but can be set up 700c with a 35c max tire size. You can only set it up with brakes running 650b.
The Single Speed Bolt now features removable Canti/V-Brake Mounts and cable guides! The posts are welded in the "650b Position". So if you want to run 700c you'll have to figure out a different braking scenario.
It makes for a super fun Randonneur style bike, commuter, or all-around-do-whatever bike.
If you aren't too keen on the fixed/ freewheel single speed life, you could also set this bike up with an internally geared hub. Orrr if you want to keep it real simple and still have a brake you could just throw a coaster brake on the back. The possibilities are numerous.
Designed around a 650b Wheel with 48 being the max tire size. You can run 700c wheels with 35 being your max tire size.
You have to bump down to a 650x42b if you want to run a set of fenders.
It is belt drive compatible and has a two bolt coupler in the drive side seat stay to sneak a belt through.
