jackknife

it has a hydraulic drive system apparently...

interesting.

anyone got a full translation?

I guess having no apparent braking system is no big deal when there is also no apparent drive system either. No chain, no drive shaft. am I missing something?

more info

Cool, but will it actually work? I'm assuming those pictures are of a 3d rendering. If there were a workable hydraulic drive system designed into that, I can't see it, and I surely can't see any brakes. I have to assume a real working bicycle would have to look quite a bit different than that.

Old Raleigh 20's look sooo much better than that.

Cannondale have an annoying habit of publishing funky drawings saying they are "bikes"...

for a second, let's assume there is a working hydraulic drive system on that bike. It must consist of a pump somewhere in the vicinity of the bottom bracket. a fluid reservoir somewhere above that. A drive mechanism similar to the pump. Hoses connecting the reservoir to the pump, the pump to the drive, and the drive back to the reservoir. Then add maybe 8oz+/- of hydraulic fluid. I'm assuming that the pump is integrated with the bottom bracket spindle, and the drive is in the hub.

Anybody have a rough guess how much that rig would weigh compared to a chain, cog, and sprocket? And you better hope that stuff is dead reliable because most of it it is housed inside an aluminum frame with no apparent service openings, not even a cap for adding/checking fluid.

I would think a hydraulic drive system would be nasty as far as weight is concerned.

looks like a multi-tool with flat tires.

The bike doesn't even exist...and it's already getting trashed.

i'd rather have a moulton.


partly because it actually exists.

Guy comes on and says: "this is the only folding bike I would ride".

That's not a bike, it's a drawing of a theoretical bike that wouldn't actually work in real life. When I was 7 I drew some rocket bikes that looked pretty fun to ride too... but why would someone prefer to ride a pretend bike that wouldn't even work over an actual bike that would? A tricycle would get you to the store quicker than a drawing of a rocket bike. Just sayin'...

A rocket bike would be so awesome. Just like the flying cars we got in the year 2000. I remember a kid used to draw his tank/helicopter transformer creations in class all the time. The bike looks kinda cool. I wonder what it'd ride like?

I'll stick to with mine before going with that Cannondale...if it ever hits the market. That Swift on FGG is nice too.

Here is mine: https://velospace.org/node/557

Acavengo, how do you like your Dahon? I still have plans to build a packable fixie a la yours or the Swift at some point....

Here's a foldable bike I would ride! Heck, it is the foldable bike I ride!


The above is prior to taking off all the unneccessary items such as the rack, fenders and reflectors.


This is a crappy phone cam shot of it after stripping it down. I'll try to get a better one later.

It's a Dahon Boardwalk S1. Factory-built as a coaster brake singlespeed with a front brake but the fixer in me fixed it up right away. Gearing is 48x16 with 20" wheels so roughly 56 gear inches. Looking to pick up a 52-53T chainring and a 12-13T cog to bring the gear inches up to around 75-82 gear inches. Other than the low gearing I like it. I can pull skids but riding no handed is a bit obbly. A big plus is it fits in my little Honda CRX a lot better than my full-sized fixie. It was originally purchased because the ad agency I work for was pretty much deadset on moving from NJ to NYC and I was planning on taking the PATH with my full-szed fixie but then found out I wouldn't be able to do that until after peak hours. Enter ebay and the folding bike. Turns out my company resigns the lease in the building we're in for another year and leases half a floor in NYC for client meetings and the like. Boo! I was looking forward to riding around the city on my commutes to and from the PATH and during my lunch hours. Oh well... We'll see what happens when our lease expires next fall....

The Boardwalk when stock sort of sucks, but with my conversions I love it. I ride it around 18 miles most days and the bike that used to be my regular commuter now just sits in a closet at home. That bike is going with me on my next vacation. It fits very easily in a airline legal suitcase.

If you are ever in NYC and want to do a test run on it just shoot me a PM.

I'll be around, actually...

I'm presuming the seatpost and steering column are adjustable?

+1,000

that dahon is the **** btw!

Thanks! I know you're talking about acavengo's. His is pretty hot eh? I'm hoping mine will eventually come close to acavengo's.

no, i was talking about yours. swifts are a bit techy for me.

Both are adjustable, though the steering column now requires a 10mm wrench b/c I had no need for a quick release there.

If you feel like riding it when you are in town PM me or email me at andres at correal dot net. I work in Manhattan and will be around on the dates you mentioned.
