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 ...

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 ...

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 ...

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.

To answer your specific BMX Bike The King Gap XL 2021 will support pegs. It's safe to say that any freestyle BMX bike will support pegs. If you were buying a BMX race bike, there's a chance it doesn't support pegs; BMX race is more focused on being lightweight than freestyle BMX. Can I put pegs on any bike No, you need to have a certain type of axle to put ...

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 ...

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 ...

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 ...

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 "...

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.

You don't need trial and error and you don't need a chart, you need math. (Chainring teeth / sprocket teeth) × tire outside diameter = gear inches Rollout is just gear inches multiplied by π. Tire outside diameter can be approximated by adding double the tire width to the bead seat diameter of the rim, so if you've got a tire that's (for instance) 44 × 406 ...

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,...

Its definitely not for stability, its a trick called "Table top". The flatter they look in the air the higher score.

The easy solution is usually better brake pads. If you're using $2 brake pads, or just old worn ones, you're not going to get very good braking. Spending $10 on a pair of decent pads can make a huge difference. As well, make sure the brakes are set up properly, especially if you're using two finger (short) levers. With new cables, true wheels and minimum ...

I see no bike - I see some scrap metal that used to be a bike, and could be a bike again if you add the missing parts. Clearly visible is a 1 piece ashtabula crank which is not a high quality design. Also there is no reinforcement gusset between the top and down tubes so its not built for impacts or stunting. Whoever told you it was valuable was ...

Looks like a Free Agent Limo 24 BMX" bike, circa late 80s to early 90s. Here's a BMX museum page with very similar looking one. To find the model, I just typed "free agent 24" into Google image search and the second result matched the bike.
