I'm on the committee of an annual charity bike ride that goes the length of Vietnam. This year, we had a pretty bad accident and so we're looking at how safety can be improved for next years ride. So I'm here to ask for people's input, because most of you are far more experienced than any of us.

Firstly, a quick overview. It's a month-long ride down Vietnam, averaging about 80km per day (although some of the longer days are 110km in the mountains). There are 20 riders and 2 support vehicles, so nobody has to carry anything on their bikes during the day, and any technical problems with the bikes can usually be fixed because there's a spare bike to cannibalise. We also have a rule that none of the riders are allowed to ride after dark.

So far, we've re-routed sections of the ride, so that we almost completely avoid the dreaded highway 1, which is where the accident happened (if you're ever riding in Vietnam, avoid that road). Basically, a truck overtook her and didn't give her enough space and she ended up under the wheels. That's not unusual in Vietnam, even with vehicles overtaking coming the other way. We're now pretty confident that the route itself is as safe as it can be, without cancelling the event altogether. We've also discussed the possibility of limiting the riders from 20 to 16, although because it's a charity event, that could reduce the amount of money we bring in.

The road conditions are varied and changeable. Most of it is beautiful tarmac, but a good section is fairly badly-maintained tarmac, and small sections are completely unpaved, jagged, muddy sections that any reasonable person would only use a mountain bike on. Some sections have a dedicated motorbike lane, which doubles as a cycle lane. We've tweaked the dates for three years now to find the right weather conditions, and I think we've finally got the best time of year to do it (the problem in Vietnam is that nice weather in the North, is during rainy season in the South, and between the two is hurricane/mudslide season in the middle).

My main question is on what bikes to recommend to people. Most of the people are 20-somethings on a limited budget, who are only living here temporarily. As such, we don't want to put people off by saying you have to spend a grand on a bike that you'll possibly never use again and struggle to sell/bring home. Most participants are also pretty inexperienced cyclists, certainly as far as touring goes. So far, most people have been using these really cheap ($200-300) Chinese-brand road bikes. They just about get the job done, but I can't help but think that they contribute to some of the safety issues (particularly in terms of grip on the road).

We've discussed banning road bikes completely for next year, and making everyone get mountain bikes instead. Or certainly strongly recommending it. Do you think that's a good idea? Obviously it will slow the pace quite a bit (although maybe that's safer). Some have suggested cyclo-cross bikes are a better compromise, although their availability is quite limited here in Vietnam. If you were going to choose an ideal bike to do this trip on, what would you pick? And what would you pick if you were on a pretty extreme budget?

Are hybrid bikes available? I find them to be a nice compromise for some of the bad roads and gravelly areas in the North Central United States, and will go off road if necessary. 32-40mm 700c tires seem to work best, but the thinner 28mm or even 25mm widths may work better for an event. These give you straight bars for upright riding position and visibility, a bit beefier frame for durability, and a fairly easy to afford frame style. You can get anything from low-end to high end hybrids. They seem to have evolved from road bikes in the 1990's, about the same time as cyclocross bikes. Good for tyros, easy to handle, probably more plentiful. I do not see how 80 km a day would be much of a stretch on a hybrid, but I'm not expert on the route or road situation there.

Not trying to have a pop at you, but the question asked was bout of safety after someone was run over by a truck, and you are asking if hybrids or mountain bikes would somehow be safer ? Not quite sure what you are looking for ?

Other than being as careful as possible I've no idea how to avoid getting run over, but on the road surface question, I'd have thought a cyclo cross or tourer style "road" bike would be good - rather than a "mountain" bike for (mainly) tarmac

Sorry, but fail to see how the bike affects grip to any great degree. It's not like a m/cycle or car where the suspension may be at fault or badly set up - either the frame works and doesn't break or the other thing. Tyres might affect stability but at low to average speeds even they will have limited effect. I'm afraid [like many third world countries] "might is right" in many cases and the type of bike is pretty irrelevant [assuming it can get the job done] and you may be better trying to hammer into your riders the fact that THEY are the smallest and most vulnerable vehicles on the road and to assume that ALL other vehicles either don't understand/care about cyclists.
One final thought, you say the riders are in many cases inexperienced in touring - it may be that reducing the distance per day may allow a little more flexiblity to slow up/have a breather. The distance may not be great but they are not tootaling down the local high street and as you have proved things can go wrong.

When I read your post, I had the same thoughts as sidevalve. Unless the cheap road bikes are dangerous, then I'm not sure what they'd have to do with the safety (and unfortunately the casualty that occurred would appear to have nothing to do with the type of bike or tyres used). It also sounds like the roads are suitable for road bikes as well. If the state of the bikes is an issue, perhaps implement a mandatory safety inspection? I like sidevalve's suggestion of limiting the distances too.

It seems the biggest safety issue is not the cyclists or roads you've chosen, but the other road users. Aside from route choice (you've done that), bicycle suitability and maintenance (possible bike safety check) and advising participants of the dangers and need to be aware of other road users (I'm sure you've done that too), there's not much else you can do. It might be a good idea (which again you probably have) to have a contingency plan so that you can suspend the ride quickly and efficiently in cases of extreme weather or if there is a road diversion that makes it dangerous. Being able to communicate with the riders quickly is probably a good safety point.

But you can't eliminate every risk. And I'd think the riders know there's going to always be a risk involved.

I think if you post this on the https://www.crazyguyonabike.com forum you might get more responses from people who've cycled in that part of the world with some specific suggestions re safety there, buying bikes locally etc. (maybe it's just me cos I mostly read Asia-related stuff on cgoab but this forum feels a bit more UK/Europe-centric and whilst cycling is the same everywhere, local knowledge helps.. ). If it were me I'd say there are things more important to safety than bike type, such as rear-view bar or helmet mounted mirrors that give a good constant view of the road behind without distracting from the road ahead (takes time to find one that works), and high-visibility even going as far as blinking lights in the daytime.

Definitely this; I freely admit to never having cycled in Vietnam. People who've done it are bound to have better safety tips than an armchair warrior like me :smile: There's nothing like real experience.

Cant help but think the safety issues are more to do with the route you are sending these people on rather than bike design and tyre width. People dont routinely fall off bikes with 23mm tyres for example.

Toys R us sell cheap bikes at a lot less than $300 dollar chinese bikes but that doesnt make them dangerous.

I'm not after a bike that will stop you getting run over by a truck, that was just the catalyst for the safety push on next year's ride. My question about bike types comes from a variety of situations where I suspect a mountain bike would've potentially avoided someone falling off. Here's 3 examples:

1. You're going down a hill and you hit a bit of gravel or mud that's collected on the surface of the road. You make a mistake and break at the wrong moment. Would larger tyres give you a greater chance of holding it and staying on?

2. You're driving along a fairly road wide enough for 2 vehicles and nothing else. A a lorry is coming in your direction, when a coach decides to overtake it. You have no choice but to go off the road. If you're on a road bike, that probably means you fall off. If you're on a mountain bike, you might be able to stay on.

3. You're going along a road made from huge flagstones joined together, that have a drainage gap, the exact same width as your tyres between them. You can guess what happens next.

All 3 are real examples btw. Am I talking bollocks by assuming that all 3 could've possibly been avoided on a mountain bike?

OK, makes sense. If it's any guide, a mate cycled to India on a Dawes Galaxy, which is a road-oriented tourer

http://www.thehindu.com/news/cities...m-tour-to-promote-humanity/article2438780.ece

And the traditional UK style touring bike is OK on gravel tracks. That said, something with somewhat wider tyres might help in the scenarios you mention - the ideal might be a cyclo-cross bike or a 26" wheel tourer such as the various Thorn models - though if you're buying locally, I guess you'll be stuck with what's on sale. I'd absolutely not get any form of suspension for the use you describe - but a "hybrid" type no-suspension type bike might be a good bet. I'd also get smooth tyres not nobbly just to reduce effort pedalling.

A couple I know toured in Vietnam on a thorn tandem - flat bars, 26" wheels, fairly heavy duty model, and had a great time.

I don't think the distance is an issue tbh. They're all inexperienced riders, but they do train for months prior to the ride to get their fitness up. In 5 years doing it, we've never had anyone fail to get to the destination in time, and that's with regular photo stops. That's one of the reasons why, if it's necessary, the slowness of the mountain bikes shouldn't be a big issue. It's worth mentioning that when I did the ride 2 years ago, we had two older riders with us. One of them was an experienced triathlete and the other had had a bike purpose built for the trip after consulting with a specialist shop. Both showed up on mountain bikes (admittedly one was a carbon fibre one that was almost lighter than our road bikes).

Why 26" wheels? Not that we have much choice. I don't think 29" have made it here yet, but just out of curiosity. I'd have thought 29" would be better for distance cycling.

Thanks for the input everyone btw.

A small group of us did an unassisted ride 5 week ride through Vietnam, Cambodia and Thailand (earlier this year). The bikes that coped best with the roads were hybrids with touring tyres. They cope very nicely with the decent tarmac and even more nicely with the rough (ie, missing tarmac) bits. I would not have liked to try it on a mountain bike - it would have been far too heavy.

26" as opposed to 700c "road" style. I guess 29" is the new 26" these days
