I already have a folding bike, a Dahon Mu P8, but have an itch to scratch for a Brompton. I'm considering taking the train to work after 4 years commuting over an hour each way in LA traffic. The Brompton appeals to me because of its smaller fold and ease of rolling when folded. Also I like the assortment of carriers.

So I did a test ride yesterday at Electric Bikes LA. It didn't go very well. I did a test ride there about 3 years or so ago. But this time I have bad chronic neck pain. I had pain during the earlier test ride, but now it's much worse. I can't lean forward much at all. I'm still an avid cyclist, but must ride a very upright bike. My regular bike has a fairing to partially compensate for the extra wind loading. I don't expect to use a fairing on a folding of course. But I do expect reasonable comfort.

I'm 5'10" and have longer legs roughly those of someone at least 6' tall. I extend the seat post on the Brompton almost all the way up minus an inch or so. I tested both the M type and H type. I focused more on the H type because of the more upright riding position I desire. But afterwards I read the H type is slightly more forward. So wonder if I should have also focused on the M type a little more. I even tested with the seat all the way forward

Bottom line: I'd like to make the Brompton work. The bike shop is one of there better dealers. Yet I didn't get the sense they understood how to work with my special needs. I can't help but wonder if there's a work around for someone with my physical limitations.

My other option is to make the Dahon Mu P8 work for me. I find it's ride at least tolerable pain wise and handles much better. I'm over extending the riser higher than Dahon recommends. But it still feels solid enough. I've also read where the Brompton is more often tolerated in stores, restaurants, etc. than larger folders. But that could also be hype.

Any help or ideas will be appreciated!
