It's to ensure that young boys who ride BMX bikes will be able to have children when they grow up. Fine print: More accurately, it’s to assuage the worries of the parents that are buying the BMX for their young male child that they might not have grandchildren. Actually efficacy for such purpose is under debate.

It's to give the illusion of safety.

What harm could it possibly do? The cranks are held firmly in place by the bottom bracket; the back wheel is held firmly in place in the drop-outs. The chain is completely non-structural: all it does is transmit power from the pedals to the rear wheel. The only issues I can think of are make sure you know how to remove and replace it, obviously; I pretty ...

I'm 65, and doing 60-70 miles a week on local roads, trails and hillsides. I'm not a kamikaze biker anymore, but it's still wholly worthwhile. Injuries just take longer to heal, and I'm not so patient anymore. You're only in your 30s and you're wondering if you're too old? Find a safer sport, buddy. Ironically, I'm wondering when I'll be too old. Not even ...

People were doing tricks on bicycles almost as soon as they were invented. While I couldn't find references about curb hopping in particular, I'm pretty sure that these tricksters from the late 1800s wouldn't have had a problem pulling it off. Cyclocross has roots that go almost as far back. The first organized cyclocross races were around the end of the ...

We just pulled the front wheel up and dropped it as we went over the curb, then we kept riding, letting momentum pull the rear wheel over the bike. It's what I still do. (I don't have a BMX bike.) Sheesh. So much fuss over a simple and second-nature action we never even gave a 2nd thought to.

I accidentally found the answer to this question by... listening to Judas Priest. Yep. Here's a picture of Judas Priest "Painkiller" album cover: You can see the exact same "double fork" imagery, which reminded me of this question I read months ago (it's actually a common logo they use, not just on that album cover). It turns out a ...

Note that if you have a penny farthing, then hopping curbs really isn't much of a problem. You do have to be careful not to do an end-over but a bit of leaning back on the saddle or hooking your legs on the front bars would do the trick. Some various positions for penny-farthing MTBing: Note that solid rubber tires had an advantage over modern pneumatic ...

Sounds like the handlebar stem is loose. This is an extremely dangerous situation and you should go immediately (pushing your bike or taking it in a car, but not riding it) to your local bike shop to have it looked at. The fix is easy and should take less than 5 minutes (and only a few dollars/euro if they charge you at all), but again it is critical that ...

If you don't have a chain and don't have a chainguard, you're almost guaranteed to slip at some point and dig your chainring into your shins or ankles. It's very painful -- both at the moment as well as later when trying to get the grease and grime out of the puncture wounds... If you do decide to take off the chain, you might consider wrapping a very ...

No, age will not restrict you. You're not as young as you used to be, but in a good way: you won't have physical limitations of age, but you'll be more observant and thoughtful about what works for you and what doesn't, and less likely to take a "walk it off" approach to injury. Age-related losses have not set in. In short, you're fine. One ...

I ride a pro racer XL BMX. They are built for speed. I keep my seat down for 2 reasons. all my pedaling is done standing up -- power is everything for a racer. My saddle is made of one material only -- composite material -- its like sitting on a steel plate. I only use it to coast on and relax -- and that is only after the race. However, If I have ...

Verde BMX at http://verdebmx.com/completes/ They appear to be based in Columbus, Ohio, USA. Method: I did a google image search for "BMX logo leaf" because it looks like a leaf to me One of the images is this, which looks kind of similar Following the link to their web site gave me this answer

The logo is that of Mirraco BMX, which was started in 2006 by the late Dave Mirra. Mirraco got out of the BMX business in late 2013 or 2014. You might be able to match up your bike with some of these on RBikes.

The ISO freewheel thread standard is 1.375" x 24tpi Most freewheels I have encountered have been ISO. Some hubs use "British" threading at 1.370" x 24tpi If you use an ISO freewheel on a British thread, it will work, but you should check there is enough thread engagement to avoid stripping the hub. The trials-oriented retailer TartyBikes suggests 9 thread ...

If you are 5 foot 10 then you will be fine on a full size 20" wheel BMX. Each model size will be built for the specific wheel size, things like tire clearance and brake positioning will normally mean you can't increase the wheel size. You might like to research how top tube length and bar rise affect the handling of a BMX for jumps and tricks. There is a ...

According to this site on artisitic cycling they refer to a trick called a "head-tube wheelie" which is probably a good name for it. BMX enthusiasts may have a different name for it, but that's essentially what it is. I was also able to find this other site referring to headtube wheelies. Also, this Youtube video refers to it as a headtube seated wheelie, ...

what spacing is the is the rear hub? I bought an s2c recently to commute on my track bike, two speed internal geared hub with a gain of 38% but it might be over kill for yourself. Given your setup you have a gearing of about 55inches, if you were to switch out the rear cog to a 12 tooth you would gain 5inches, bring you to around 60 which is considered a ...

Unequivocally, yes, you can - it's just a matter of whether or not it's worth it to you. Without seeing pictures or details: to avoid unnecessary added expense, you'll want to stick with frames that have: The same head tube diameter, so you don't have to replace the headset The same bottom bracket shell width (usually 68mm or 73mm), so you don't have to ...

Jumps takes time and effort to do right. If you're going to rush or do a half-arse job then don't even bother starting. Design is important - you need to consider run up space before and run out space afterwards. Make the jump wide enough to give options - a metre would be a fair width unless you're making it difficult on purpose. Bailing-out options - ...

It's a trick -- it looks good on camera and would count for points accordant with degree-of-difficulty and "sticking the landing" at an adjudicated comp. The bike and rider become effectively parallel with their upright-riding stance; as opposed to perpendicular when in contact with the ground. It's also a marketing cliche in biking. Like an "ollie" or a "...

Most BMX Levers are "Standard Pull", which means they have the shorter pull and are typically paired with road bike brakes (caliper, cantilever, mini-v, or road disc). Mountain bike brakes (like v-brakes, or mtb disc) typically pair with "long pull" levers, which pull more cable. This is also known as "linear pull" So, if you use a BMX lever with V-Brakes ...

Looks like a "We The People" bicycle logo You can find the logo in several of their bike catalogs. This is one of their 2010 catalog with the logo on the cover When asking questions please be sure to include any information / clues you may have. Your comment "said to be WTP Justice" was the key to finding the logo.

Is it possible you tightened the pinch bolts before tightening the bolt that runs vertically and holds the top cap down? If you do that, the entire assembly won't be fixed tightly on the vertical and will allow side-to-side play. I did that once and the symptoms were exactly as you describe. To check this, loosen the pinch bolts and the bolt in the top ...

It is possible. There are a lot of 20in wheel bikes with gears. There are some problems, though: The frame might need to be opened so that the larger hub can be inserted; There are no derailer hanger in bmx frames, so you'll have to use an adaptor, or a simpler derailer model which is mounted together with the axle; The derailer itself is closer to the ...

My son wanted to change his freewheel/cassete hub to a freecoaster hub so I did some research about 6 months ago and found this great YouTube video from Odyssey and RideBMX magazine all about freecoaster hubs. As you said, the cranks will not move when coasting backwards. For my son, this is the real advantage and why he wanted the hubs. Landing a 180 out ...

BMX was originally (and still is) run on smooth dirt track that have obstacles such as jumps and whoops (also know as the rhythm sections). Because the tracks are smooth a small fully rigid bike works amazingly well when ridden appropriately. The BMX bike and track evolved together emphasizing a riding style that is about timing and body position. All of ...

As far as I'm aware, it's all about the rider's location vs. that of the rear wheel. A short chain stay helps, because it tucks the rear wheel up closer under your center of gravity. What really makes a big difference is the tilt of the handlebars: When the handlebars are rocked backwards, it lets you get your center of gravity way back past the rear wheel,...
