New to me Dahon Helios, have questions

I bought a Dahon Helios P7 off of Craigslist about 3 weeks ago. It is my first folding bike, though I've owned many bikes over the years. I recently took a job in a city where parking is a nightmare. After an hour commute, I park in a parking garage, and don't want to drive at lunch time and have to park again in order to eat. Santa Monica and West LA are very different from Orange County where I live. A folding bike makes a lot of sense.

My particular Helios has a fixed handlebar post height. Some of the newer models, have an adjustable height, and the cross bar pivots the hand brake angle when folded. My model does NOT have that option, but I've managed to find a compromise brake angle. Is there a way to upgrade my front post to the newer design?

I want to add a rear rack so I can haul groceries. I have a couple panniers already, that were intended for my recumbent, but never used. I noticed Dahon has a rear rack designed for panniers called the Traveller Rear Rack. Is this a good option?

I also could use a mirror, preferably something small and light on the handlebars, that won't interfere when folded. Any recommendations?

Steve

Helios is a great bike.... however some years have different handlebars.... I could show you the difference on my website, but wont give any links here....

the older ones have a stem with an expander bolt.... the newer ones have the radious 3 handlepost which comes in various configurations.... T handle with aber hallo ... or adjustable with a seperate top section, or comfort with additional top section ... or jetstream with top clamp but considerable shorter for a very low sporty ride....

traveller rack will fit .. as long as u use small panniers you should not have any heel strike

Best Thor

For some possible options see:
Handlebars, Extenders and Bar Ends
but check with Thor before ordering.

There are alternatives:
  • Rear racks, such as those from Carradice, that hang from the seat and hook either to the stays or the seatpost
  • If the Dahon as a truss in the front, you could hang the Kanga front rack

with that rear rack you wouldnt be able to get the seatpost down, and hence would bend the front chainring when it hits the ground, when you fold the bike....
Kanga doesnt work with the Helios as the bike doesnt have the 2 or 3 hole attachment found in later Dahons ( and Terns )

Carradice's Bagman2 does require (un)screwing the rack each time the user wants to raise/lower the seatpost. But the lower alternative part could maybe be screwed onto the seatpost instead, so the user can just remove the seat/seatpost when folding.

However, for lighter use, Carradice profites a rack that just hangs from the seat and uses a quick release solution. But it might not be enough to carry groceries.
