Hello, when pushing on the Sofrider I (6ft) did not like the feeling that I pushed at a downwards angle. I once tried a HP Speedmachine and loved its forward push feeling, having no problem with its 30 seat back . Saturday night I envisioned a smaller rear wheel to rise up my feet on my Sofrider V3 - like the late Valdo's model: I even ordered a 20" wheel on Saturday night, but woke up on Sunday morning and immediately got the idea to put the 16" front wheel of my HP Spirit - a short LWB recumbent - in the position of my Sofrider's back wheel to get a more reclined position while keeping the good body angle I set up while riding on the home trainer. So we have - both unused - a SON dynamo and a Magura Julie brake disk there. I inflated the tire to just under 5bars (70psi), that was OK: Unused Tektro back brakes - I rode cautiously, and the front brake was enough. Keep in mind that I was just position testing on lonely roads well-known to me, never take risk at this!! A lot of space for the bag: ...and a more reclined position, which I really enjoyed, I only made small adjustments to the leg length: Well, it does not look fast or sexy, but it felt comfortable and swift, and the feeling that the feet were higher was good! (I just created a thread in the Ride forum describing the landscape a bit, for those interested in landscape pics) After cruzing and enjoying myself for 2,5 hours my thighs "told me" to better drive home. To calculate the angle change: the 16" wheel's radius is about 195mm, the normal 26" wheel's radius is about 315mm, so the back axle sunk by about 120mm. This leads to about 6 more recline - at a wheelbase of 1110mm (taken from the data sheet). The steeper steering tube angle means you need more force when straightening the steering wheel at the end of a turn, but this was unnoticed with one possible exception: when I tried a slow&tight turn on a 2m wide lane, I did not manage to stay on the tarmac, got into half-high grass and was practically stopped by the uneven ground - the bike fell under me - one possible reason for my failing might be the added force to upright the front due to that steeper angle. But this was extreme. Today the 20" wheel arrived, and I expect the tube&tire to arrive soon, so I can put the 16" wheel back on the HP Spirit. To continue the testing at a different angle I also ordered a Quest-style short (125mm) suspension element K261 to modify the suspension length, too - currently the K258 at 165mm. I know it is not the same spring ratio, but they are not expensive (for me) and I am curious how it feels: more reclined, but harder suspension... My neck accepted the change without problems. My slight groin pain - just above the hip joints - did not come back until today, although I pushed sometimes. Maybe I should try Q-rings, too, to get rid of this pain... That one was really Happy Cruzin' Ernest P.S. It also worked well on my home trainer today!! I will put some brake (drum / disk) there if I decide to keep a smaller wheel in the back.
