What you experienced was brake fade. There are two reasons why it happens: The fluid inside the brake boils releasing gas into the system which makes the brakes feel spongy and then non-existant. The pad and rotor heat up sufficiently to not work, this feels like you are applying the brake but it doesn't work. You look to have experienced the first. ...

An alternative to long tail bicycles is long wheelbase bicycles:

Recommendations for transporting twins on a bike? A trailer. I'm a father myself - my son is nearly 9 months old, and I cycle a lot. In the area that I live, I wouldn't feel safe having him on the road with me at all. If I were offroad, or on more quiet roads, I would definitely prefer to have him in a trailer; they're more stable for you and your child ...

One-wheeled trailers are more agile and don't increase the width of your bike. They lean with the bike. If you're going to go really narrow places, you need one-wheel. Two-wheeled trailers can generally carry more weight and are less prone to making the bike fall over when you stop. So, what are you going to do with the trailer? Going up and down ...

Delicate items would probably survive best in a small backpack. Your body acts like a natural shock absorber so anything strapped to your back should get the smoothest ride, especially if you're out of the saddle for the bumpiest sections. Remember to keep the pack light though. Put heavier items like milk on a rear rack, rear panniers or ideally on a ...

He is 3..... he will do what he wants to, when and how he wants. I had a lot of trouble getting my boy off trainers (We did not go don the balance bike path). After many attempts involving removing them and putting them back on, I gave up and decided when he is ready (or old enough his peers laugh at him), he will want them removed. One day he just came up ...

You could always get a seat for one in front of you (handlebar mounted child seat) and the second behind you (conventional rack-mount child seat). Probably have to have them trade off to minimize fights, since the front seat is probably a lot more fun (and easier to watch the kid). I see a couple around town where the wife carries their kid in a handlebar ...

I don't transport a lot of groceries, but physics tells us that we really shouldn't worry about going up and down so much, but that we should worry more about things getting knocked around. An egg in the carton shouldn't break simply because you accelerate it quickly, it's going to get broken when it takes flight and then falls back down. Uneven pressure ...

Advantages of a one wheel bike trailer Easier to add suspension Less wide (less likely to be hit by a motorist) Advantages of a two wheel bike trailer More stable at low speeds Climbs better (since it does not need momentum to remain up right) Probably has more cargo capacity Easier to make

Followed some links from your links and found the actual text of the law, which summarizes the law as: Prohibits person from carrying child under six years of age on bicycle or in bicycle trailer. Elsewhere in Oregon law, a bicycle is defined as: [a human-powered vehicle] designed to travel with not more than three wheels in contact with the ...

This is pretty unconventional and not necessarily available to you, but here's some food for thought. Friends of mine had had a custom 'rack' built for their Kona Ute by a local rack & frame-builder to transport their two daughters (although they are much older). It came out exceptionally well (plus the girls love it): (Photo courtesy Lois Keenan, ...

buy cases of beer with the cardboard dividers between the bottles. You can then re-use the cardboard dividers in other cases of beer.

The simple answer to your question is yes, people have built surge brakes and they do work. Specifically, I have built one, but I called it an inertia brake. This page has some notes and photos. The mechanism was fairly simple and robust, a telescoping towing arm with a couple of standard brake cables leading to V brakes on the front wheels of the trailer. ...

If the child's bike has a quick release front wheel, you could also use a universal fork mount bolted to a rear bike rack. Then just hang the front wheel on the kids bike with a bungee cord.

These hitches don't work very well. They don't grab tightly enough, so they can twist around the bar and bump in to the wheel. As they twist they will take off the paint. They also require a lot of turns to attach and remove. I had two trailers with this kind of hitch, and 3 bikes to pull with. I bought this Burley flex connector for each trailer: I used ...

I just built a trailer based on the Wike DIY kit. I decided to make it after seeing this great looking trailer. I don't have experience with single wheel trailers. I am happy so far, but my experience has been very limited. The intent was to use it for local cargo runs - not long-hauling/touring I'll report more here as the months go by Here is a ...

I buy all my bike lights from http://www.dealextreme.com - they are in HongKong but have free postage to Canada. You are just buying the same made in China stuff in the shops direct from the makers in China. Avoid the very cheapest stuff (destined for a Dollar store near you!) and check the reviews. edit: specifically for your trailer you can't beat this ...

I'm not aware of a commerically made one, I suspect the barrier is liability issues (and possible legal issues in some places). FWIW, the limits in Australia and New Zealand are the same as for any other vehicle, so the main restriction is that the trailer can't weigh more than the towing vehicle (note below). Other jurisdictions may have different rules. ...

I bike all winter long, down to -30°C, there are some definite tolls to your bike at colder temperatures. Unlike a vehicle that warms up after the engine has been running for a while, bikes stay cold when you ride them cold. There are two things I notice the most, air pressure is definitely one of them; cold air shrinks, and low tires drag, so if you're ...

My personal experience is go with the one-wheel trailer... you won't even know its behind you if you pack it balanced. My trailer is just like the first picture and while I was training for a 100+ mile ride - I loaded it down with gallon water jugs... and if I got really tired pulling it I just poured the water out(usually some on me - it gets really hot in ...

A trailer with a 100# capacity fully loaded over the axle is unlikely to cause significant damage to your bicycle frame--even using the attachment device shown for the Rhode Gear trailer, above. The "tongue weight" of such a trailer would probably be in the twenty-to-thirty pound range. Just don't load this trailer--or any trailer--with all of the weight ...

For what you are asking about I would recommend buying a used kid trailer (for about $50 - $150), cutting off the fabric and adding some kind of floor/bin. Interestingly enough most child trailers are rated for up to 100 pounds were as the BOB trailer is only weighted for 75 (if I remember correctly). The only advantage of a BOB or Extra wheel trailer is ...

Depending on how comfortable your kids are on a bike, you could get something like the Trail-a-Bike Tandem It's as narrow as a regular bike. I don't have any experience with it, but it seems like it might work. Xtracycle also have various bolt on longtail attachments for regular bikes. I'm not sure if two four year olds would be too heavy on a longtail, ...

Lets put some physics to play (mostly because I want to do some numbers....) Assume the brakes did all the work..... 200kg all up weight of rider, bike, trailer and kids. 350Meter vertical descent means you need to dissipate 700kJ of energy = 200WH. I found a reference to "Road and mountain brakes must absorb 75 watt-hours of energy over a 15-minute ...

Though there are some very good answers here already, I get the impression you are more interested in why the brakes suddenly stopped working after you stopped riding for a moment. I am not a brakes expert, but I have a solid background in thermodynamics. From that perspective, it sounds like what happened (as explained above) is that you had boiling ...

I don't think this has ever been done before for a lightweight bike trailer, which would mean no, there aren't any proven approaches to using surge brakes on a bicycle trailer, but I've got some ideas... It would be very impractical to use any current trailer surge brake options on a bicycle trailer, they'd be too clunky, heavy and wouldn't be compatible ...

If you have the requisite skills you could make one of these (or get someone to make it for you): There are lots of details on his site Rutzer Tales.
