Cargo trikes

From slow bikes on Facebook conversation I started

I am thinking of getting a Christiania cargo trike, I am in East London and would be a very early adopter. I have balance issues and have been researching extensively. I would love some first hand views! I understand there is a risk of toppling and hip fractures. I would get electric assist. Is this a boldly go or Houston we have a problem issue?

With some careful training and care, it is not that easy to topple a Christiania bike. One only needs to ride a bit slower when turning. I’ve some experience of Christiania Light and on downhill it might be a bit unstable, so I wouldn’t recommend it for a person with balance issues. Especially with electric assist. The bigger and heavier Christiania is the more stable it is. Trio Bike would be maybe more stable, so I’d recommend you to check out their options too.

Clive Durdle I thought tadpoles were stabler than two wheels at the back

A few years ago, you could have popped over to Fitzrovia and bought one from Andrea at Velorution, but now I recommend Practical Cycles, which Simon Thornton linked to above. I’m currently stuck in the Blackpool area awaiting my escape to civilisation, so it’s my ‘local’, but if you want to try some trikes, DO arrange beforehand, as their shop is not often open, being an online business for the most part.

Clive, contact my friends at Tower Hamlets Wheelers, the local lobby group, they will let you try one out: david@towerhamletswheelers.org.uk Tell them I suggested you contact them, I used to run Wheelers and the person who now runs Carry Me Cargo Bikes was also a member of Wheelers

When I hit the mainland, I’m going for a Christiania longbox with door, for the dogs!

Maybe I have been looking too much at google scholar, and I know this is about motorised types, but are there basic question marksabout rollover, yaw and shimmy?

Clive Durdle Isn’t London green cycles some of the people from velorution?

That article is irrelevant to the Christiania trike. For starters it was published in 1986 based on statistics in Alabama. The article doesn’t even specify the type or configuration of trike they are referring to.

Since 1984, Hundreds and thousands of them are carrying kids to school every day all over the more advanced nations, with no catastrophies. People believing nonsense like this, then perpetuating it in an irrelevant context is how the plague of misinformed ‘Elf & safety’ garbage permeates into the mass (un)conciousness, and is part of why Britain is so backward.

I did say the problem in Alabama was about motorised trikes – you know those all terrain big tired things! And why has a Danish physiotherapist specialising in brain injuries commented to me about broken hips? There is an issue of trikes being dynamically unstable. When I tried one I was surprised how easy it is to lift a wheel off the ground. The engineering issues are all well known, what I have not found is how the real issues of rollover have been solved in particular cases Like with Christianiatrikes, for example what the steering damping does.

Clive Durdle oh, and shimmy and yaw

Rowan Goodfellow DeBonaire

The steering damper has been fitted since the first Christiania trike in 1984. Having owned a nasty undamped ‘tadpole’ cargo trike, a damped one, and three Christianias, I definitely contend that the damper and the 2 degree negative camber transform the handling. You can ride a Chris on level ground with no hands. In corners of course it’s possible to lift a wheel – it’s often done deliberately to bump up kerbs, and I’ve ridden 2-wheel fashion just for the fun of it! (I used to do that in cars for a living but that’s another group!) unless the rider makes a mistake, there are no safety issues with a Chris. If you’re really that convinced that there are, don’t buy one! It is possible to crash one just as it is possible to crash anything.

Clive Durdle Is it hard to ride?

Not at all – once you get the hang of it. I would recommend some practice before taking on passengers. It can be tricky going round corners at speed, just because you have to lean into the corner to avoid flipping over (I’ve never flipped, but I’ve come close!)

The Christiania, however, is a bit of a beast. When you go around a corner the entire front box – to which the handlebars are attached – rotates, which causes the saddle to weave under you and pulls your arms off to one side. I felt more like a buckaroo breaking a stallion than a father out with his children at the weekend.

To make matters worse, it is prone to tipping. This adds to the excitement of the thing – how the children whooped – but is not ideal from the perspective of head injuries (use helmets. We did, but not when being photographed). ” http://www.telegraph.co.uk/…/Cargo-bikes-and-tricycles…

Although :

We have used a Christiania-bike for 3 years in hilly Stockholm for our kids and for deliveries. It was great and safe! Never tipped over, its a matter of getting to know the bike. I would say that tipping on a 2-wheeler is a lot easier, especielly when parked.

Clive Durdle

The Christiania is no way proned to tipping, just don’t treat it like a standard bike, like you would not treat a van like a mini, everyone who I have sold a Christiania to, all say that it takes a week to get used to, and then it is as easy as any other bike, wonder how a standard bike would be rated fist time you rode on that.

The 2wheeled cargobikes are great too, but very unstable at 5 km/h so no chance to ride on foot paths or school grounds…

All the bikes mentioned above are great bikes and have their strong and weak points, but to say the Christiania is prone to tipping is like saying a standard bike is unstable..”

Must agree with Peter Santos on this one. The Christiania, or any three-wheeler for that matter, does not ride like a standard bike and therefore shouldn’t be compared to its two-wheeled counterparts until you have had the chance to learn how it handles. Then, the discussion should revolve around things like carrying capacity, durability, gearing, accessories, etc…

After riding a three wheeler for only a day, I found it almost impossible to tip — the learning curve is quite steep. I would, in a way, compare this to the experience of riding a standard, two-wheeled bike — except most of us learned that when we were little kids. And this, for some, creates a fall sense of how difficult riding a two-wheeler actually is when compared to riding a three-wheeler.

When we first leaned to ride a two-wheeled bike, we were (likely) all over the place because we didn’t understand how it handled. Once we learned how to control it, it then became almost impossible to fall off of because you have a handle on how far you can push it and your instincts keep you from crossing that line. Same goes for the trikes.

All of this said, the trike takes some time to learn, but once you have figured it out, I believe the advantages that come with them (carrying capacity, stability at slow speeds, etc..) more than compensate for the slight learning curve at the outset.”

“As a result of the above, I would propose that the “golden rule” might be better replaced with the following three “rules of thumb” as guidance for tricycle design:1. The centre of gravity should be mounted as close to the two-wheel axle as possible to…See More
