Frame comparison: Vigor vs Mu

I think my next FB will be either Mu or Vigor.
Can I hear some thoughts on these frames?
Don't have a chance to see them in person.

Mu doesn't have chainstay...is this wierd?
Looks like chunky seat stays...unattractive?

From pictures, Vigor looks better, more traditional.
I'm more ol' skool...maybe I should choose Vigor.

What else am I missing?

mu is lighter
vigor is hydroformed and a little heavier but maybe also stronger, although I have not heard any complaint of the mu frame being weak either


if u think belt conversion than its mu .... but in all honesty as cool as a belt is you trade in gear ratios usually. chain is much more "mod able"

I have a Mu with over 12,000 miles on it. I never noticed the missing chainstays. It's now my dedicated "winter" bike.

A more important comparison is the Mariner/Vitesse vs Mu frames from Dahon.

The Mariner/Vitesse frame has also been used in the Formula from Dahon. It is a Alu frame with a straight running section versus the curved section of the Mu. The Mu, generally, does not have a lower chainstay which has the advantage of taking a belt drive well. The Vitesse frame is, by contrast, very functional. It does have chainstays.

The bigger difference is that most of the Mu bikes are built to a higher standard with components than the Mariner/Vitesse bikes. Mariners and Vitesse pack good transmissions, have racks, fenders and often adjustable handlebar posts. Mu's often have rack and fenders as options (except USA's current Mu D10 Tour). Adjustable HB posts are common.

It is the crank set, bottom bracket and wheel sets where the bigger differences are. Mu's tend to be sealed BB's, double walled rims, and nice 130bcd or 110 bcd crank sets. Mariner/Vitesse often have loose ball BB's, single walled rims and one piec welded Crank/Chain Wheel sets. These items can be upgraded relatively easy. If you run across a Formula S18 or S20 it will be fully upgraded, and often have disc brakes as well.

The Mariner/Vitesse/Formula frame does have welded chainstays. On the Vitesse it would be nice to be able to upgrade to a nice belt drive as the internal hub is ready for it and a belt seems nicer than a polycarbonate chain guard.

A BB upgrade on the Mariner/Vitesse will do the most to close the difference with a Mu series bike.

Vigor, well, get a Vector. The P20 is a very sweet bike. Seat to Handlebar is a bit shorter than the Mu/Visc series but its got a monster wide gearing and is very light.

I'm not big into component levels because I'm just a casual rider.
There's no value in getting the best component, to me...because I doubt I can feel the difference.
I'm most interested in how a bike look and have the minimum capability I need.

I think the Vigor is very attractive frame... it must be due to the boxy cross sections of the frame. There's something about those hard edges that's masculine allure.

The Mu looks to be round cross sections...looks more aerodynamic and femine style.

The Mariners looks very generic...like the other millions of FB out there.

Da Hon is either cloned often or they sell thru all sorts of outlets and brand them for their customers needs.

Go for the Vigor! It is available now (was out of stock for several months). Hydroformed frames are quite striking design wise. As I noted, I have a Vector P20 and it looks really nice.

I did do some measures and the span from seat post to handlebar was shorter than Mu and Viscs. Not as short as the Eezz however. Very comfortable for me.

Shorter than the Mu, really?! I thought the Mu's reach might be on the short end for me.

On quick rides, I don't mind short reach, for that upright posture.
But on long distance rides, I like longer reach, in order to stretch out, lean forward.

I have a Abu Hallo reach extender thingy, but I hate the way it looks. Too big and chunky.

I was measuring the Vector not the Vigor so best to check a Vigor.

The new Visc D18 Disc version has a super adjustable stem that gives nice forward or upright positioning. More money for that bike but a sweet bike for sure.

Visc D18 Tour has a smaller (less quick) adjustable stem position.

One thing to watch for is the angle of the handlebar post. Most current bikes have a good forward kick in the angle but there are a few that are more vertical. This of course can shorten the reach.
