BTW, why no suspension?
I'm keeping an eye on your build for the moment to get some ideas.
and fast
After riding and adjusting...observations:
* The Luna C965 (equivalent) color display is worth it.
* setting the speed limit is a bit bizarre. You can set it up to 45 kpm and the next increment that would be 46 kpm goes to 99 kpm.
* 5 levels of assist and with the 52V battery at level 5 the motor is pulling 1250 watts, at level 1 it's pulling 400W.
* the Rohloff is expensive, but it is very accurate and smooooooth! Plenty of range and easy to shift. However, the motor has to be off to shift effectively so "clutching" or some other motor disengage is a MUST! This might be frustrating for some.
* The bike weighs 45 lbs!!!!

As you can imagine the bike accelerates incredibly fast. I did ride it at 32 mph and probably could have gone 40+ easily but 32 mph is more then I need. If your a power/torque/speed freak (pick and choose) this bike will feed your addiction. Even though it's setup for "upright" riding, it handles well (short) wheelbase. I've only ridden it a total of 5 miles so there is still a lot to learn and I have no idea how long the battery will last. I have to take it out on a longer ride to get a feel for speeds/gear settings at what assist level, but this setup certainly has a wide range of ability. I'm pretty sure speed, gear and assist level management has to be watched closely to avoid heat and or excessive load.
This is going to be fun!!! Pictures below

Also, what is your Rohloff cog selection? 48T/15T? Other?
Let me know if you think it will work
It is fast! I rode it to work this AM...14.5 miles over varied terrain at 22 MPH average speed. The best I have done previously is 20 MPH. When it's pulling 1200+ Watts I'm able to pedal up any of the inclines with very little loss of speed, but it does eat the battery reserve and the motor runs noticeably hotter, so I use the max setting sparingly. I decided to get the programming cable and will reprogram the assist levels and probably reduce the max AMP cut-off. I'd rather work a bit harder and extend the range.
But if you really want to go fast this bike will do it.

It's superb, everything I wanted. I ride it between 150-175 miles per week until winter in the NE sets in. With the Titanium frame it's light and strong, and the BBS02 750W @ 52V (even down regulated to max 18A) puts out all the power I want. The Rohloff 500/14 IGH is the "icing on the cake". Now that I've spoiled myself building mid-drives with the Rohloff I would never go back to conventional cassette and derailleur, there's absolutely no comparison. The IGH is far superior in every aspect of smooth efficient shifting and with the inline drive train I run a Connex 7R8 chain that is still on the bike...the original chain.How does it perform a year later?
