Re: what is it about a bmx bike that some people dont understand?

That top tube... They are getting more common nowadays. I wonder why such a weakening structural design did succeed to find a niche in the bike market. I'd be more concerned with that single sided fork. As for the frame it is Cannondale so I suspect they know what they're doing. Have you heard any ...

Re: what is it about a bmx bike that some people dont understand?

Would a BMX-based Longtail cargobike with 20-inch wheels be a "donkey"? That would never catch on. Gotta think of something clever, like calling it a Hooligan. http://community.vintagecannondale.com/attachments/cannondalehooligan-jpeg.7550/ That top tube... They are getting more common no...

Depends of its character. If it is neat and pretty comfortable, call it a mule. If it is ugly, call it an ass. If it is hard to handle, you can call it a donkey.

Re: what is it about a bmx bike that some people dont understand?

I see them BMX like ponies. I mean, small horses have a purpose. Kids often learn to ride on ponies, until they grow taller and get more comfortable on a horse. Doesn’t mean that grown men can’t ride ponies, even prefer them for sport. Polo ponies are a good example, because polo is much more exciti...

Re: very small generator

12 yrs later, the principle hadn’t changed. If you are going to burn gas to charge your battery, you might as well burn gas to ride. A 50cc scooter or lightweight motorcycle will do about 100 miles a gallon, and can be found cheaper than a good ebike. Anyway, if it is only occasionally, many portabl...

Re: Questions about Crystalyte 5303s

The X53 series are outdated. I mean, much better motors are available today. Here they are worth 100$, and at that price it is a good motor to build a fast bike on a budget. Used Lipo... you never know. That is a high risk, thus not much value unless you can test them. Still, when they are not puffe...

Re: Hardtail EMTB - A Mistake?

Riding fast does require a suspension frame, trails even more so.

At low speed and/or fair surfaces, a hard tail is fine, if you ride it bicycle style especially.

Re: Looking for a strong headlight

Trafic? Riding the streets at night in a city, ideally requires automotive standard lights. This means a 12v circuit and motorcycle light set. That is what I recommend on fast ebikes. Riding the bike path can be done with bicycle or ebike lights. Riding off road at night does require work lights, th...

If you can’t put brain in drivers, put brain in their cars. This had started for quite a while, and the evolution is pretty fast. Putting a beacon on bicycles, or in granny’s handbag, can keep ‘intelligent’ cars from hitting them, but most idiot drivers are not choosing cars for their brain...

All big cities are crazy when things go wrong. I feel lucky to have the choice and freedom to live anywhere I want. I usually avoid the city in the winter anyway. Next summer I will be living on a boat.

I buy it a the local bike shop, like everyone else I guess. :D
I buy the small kit, same price as the glue alone anyway. Not anymore though, for I ride tubeless for a while. I carry a tubeless repair kit, yet never had to use it because the slime and tire insert always let me ride home.

Re: Can rubber cement for tube repair freeze then thaw and still be used?

It doesn’t freeze, but the life after the tube is open is very limited. The solvent is very volatile and the cap is not air tight. You can use candle wax (after the cap is on) to make it last longer.

Re: 20 inch - 3" fat tire build for sand

Depends of the sand. Loose surfaces like larger diameter wheel just as much as wider-softer tires. Cutting on the wheel size might not be your best option, unless the sand is compact.

Re: How do you feel about your state's moped laws?

They are not going to change their habits for us. We need to share the streets with cars, and for that we have to be able to match their performance in the city environment. In too many places, ebiked are now perceived as a nuisance on both, bike lanes and streets. Bike lanes are used by a variety o...

This is nit a matter of motor. There is an awful lot of motors that can do it. Bicycles are another story, for very few are safe to build such a fast bike, and even those would need mods ans at least some motorcycle components. Controllers and batteries are going to be big and heavy, no matter those...

Re: Do you use an fairing or partial fairing on your ebike, emoped or BSM?

Low isn't stable. Low is tippy because the roll rate is too fast. It depends on speed. Exactly. Speed is time, and stability as well as reactivity are time related. -——-—— Then, COG is not alone in this fight between stability and reactivity. Length and size and all geometry factors, are contributi...

Low COG makes balance precision High COG makes balance reaction I always use the extremes to illustrate this principle: GP racing motorcycles that have the highest COG, and Trial motorcycles that have the lowest COG. GP bikes need to be balance reactive, meaning little action from the rider is requi...

You can have them alu, rolled to your spec at sheet metal work shops. You can make your own HDPE or PVC, with patience and heat gun. I can't imagine what having them made would cost.
