big dummy technique

Postby mekore » Wed Jul 27, 2011 5:01 am

i'm buying one, any tips on riding technique?

i'm sure special attention have to be paid on turning and braking, especially i'm planning to carry a passengger

No idea what one is? :o :lol:
Once you can climb hills on a bike it's all downhill. :mrgreen:

Hopefully I'll know what that's like..... one day. :shock: :lol:

Like the Kona Ute, but bigger I think. No idea how different they would be to ride, maybe ask some tandem riders what it's like to ride solo?

Don't try and do wheelies :D I would say just take it easy and get used to it first. After awhile you probably wont even notice the extra length.

Every time I see a photo of one of those things all I can think is: "That CHAIN!" Formidable.

no special technique, just ride and enjoy. Those fat tyres make for a smooth ride.

Hopefully mekore will get one with pedals :D

I didn't notice the extra length in a tandem - it handled like a regular bike - except when clearing humps in the road, like those very small speed humps. You are right about braking though - anticipation will be the name of your game. Good to have disc brakes

Given that the whole purpose of a big dummy is to haul cargo, I suspect you will notice the width, the wieght and the balance, especially if the weight distribution is up high or out wide.

The bikes seem pretty popular at the Cargo Bike forum on MTBR.

Have fun & don't forget to post pics & info

Cheers

The one shown at the top seems to have almost no rake from what I can see. That will make it inclined to want to NOT stay on a straight course. Fine for track racing but not ideal for lazy cruising, while the length would otherwise make for an easy ride.

Other one (blue with people) does have rake.

(Rake - the offset of the front wheel axle to the axis of the forks.)

Jack knifing would only be an issue if you're articulated (i.e. towing a trailer), surely?


how about more zippier little numbers cutting in front of you to beat you to the lights?
You'll need a sticker made up for your bags or box on the back "Only Idiots cut in Front of Big Dummies" ;)

Col, you're right in saying that it has straight forks... but if you hold a small ruler up to your screen - in line with the headtube - you will see that the fork blades are angled forward enough to give the bike enough rake to have a good amount of positive trail. Trail is what keep the bike pointing straight ahead.

The head tube angle is quoted as being 72 degrees. Given Surly's experience I would suggest, as you imply, that Surly would have a clue about getting it right.

I was looking for a video I saw of the Yuba Mondo, from the above photo URL, and noticed that there is a guy in the photo sitting on the ground as if he has been dumped. I cant blame the Yuba Mondo owner, really :wink:

And this guy rode one from Alaska to Tierra del Fuego, with those huge Endomorph 3.7" tyres.

I have one, minor bit of advice: keep your load as low as you can. I've commuted on my home made tandem (which looks to have a similar wheelbase to the big dummy) and putting heavy stuff high towards the back (like, say, a backpack in the kids seat area) can induce some pretty solid shimmying on out of the saddle climbs. Panniers are best I think, mounted as far inside the wheel base as you can manage.
So we get the leaders we deserve and we elect, we get the companies and the products that we ask for, right? And we have to ask for different things. – Paul Gilding
but really, that's rubbish. We get none of it because the choices are illusory.

I have an old mtb with the Xtracycle kit that the Big Dummy is compatible with. I use it a couple of times a week to commute on and do the grocery shopping with on the way home from work.

The few things I've noticed:

Don't try to race up hill. On the flat it is fine, and it loves downhills. If you can find a gradual sloping road with no traffic, it can be a fun bike to 'carve' turns across the slope. But as soon as you hit an uphill, you'll notice the extra weight, even unloaded.

Always load your cargo on the side that has the kickstand first. Otherwise its very embarrassing at the shops when your fruit tries to run away from you as your bike tips over.

Get used to some interesting looks and questions from people :)

As for riding technique, the basic mechanical disc brakes work quite well on my bike, you won't get up to a high speed to worry too much.

You'll find the Big Dummy a bit stiffer than just an MTB with Xtracycle add-on, the gearing also set up for cargo work, the ride really smooth once you remember that any bumps that your front wheel rides over takes a tad longer to connect with your rear wheel. You'll probably start looking for a double kickstand and the wideloader horizontal racks, just always remember that when these racks are on that your turning corners on the bikepath and negotiating the metal poles at path end is a little more complicated. You'll start to find yourself drifting to the bungee cord sections in the hardware stores and auto shops. After that you start to realise in your various trips about the place "hey, I can carry that". And it goes on from there.

You don't need the Big Dummy for that job :wink:
