I have mine slightly more forward to give some more cockpit length so slightly lower than it could be straight up, but with stock wheel and tire its 39 1/4 inches straight up from the ground to top of bars.
Bad back and old age wont let me ride S-Type stock without riser. But i found after test riding a M-type that theres some flex in the M-type bars. The S-type has none even with the AberHalo so this is the reason i bought S-type and went to the trouble of modding everything..
Measuring from center of seat post tube set all the way up, to center of handle bars set ahead slightly i have it at about 27 3/4 inches,so lotsa room and could go more if needed but also would lower height some if i did.
At 6 foot tall and long legs im super comfy with this setup. Hope this helps.
PS i got my Aber Halo from Thor just in case you wanted to know where to get one in US.
