16 Inch Trials Bike

[Apu]

To be fair, From what you have said, you don't have a clue what you're talking about, pram wheels stronger than Trials specific wheel? You ARE joking are'nt you !? And a "16 wheel will absolutly NOT stand up to trial's abuse, not even if you ride like a pixie!

This also worried me "Ten dollars will get me the bike to hack up." Hack up !?!?!??!?! bike's are'nt for "hacking up"! Also, $10 will get you some thing like this;

That's if you're lucky!

Please for god sake Just save and buy a bikie that will last longer than a day, if you wait until you're validated, im sure someone will GIVE you an old frame just to stop this monstrocioty from being born, i cant sleep at night knowing that it's going to be about

yeah pram wheels are STRONG not STRONGER. Little wheels with many spokes is a very strong setup due to the rim being so stiff. That's why you guys on your mods have good solid rims compared to the stocks with their flexible 24's or 26's. Any way if a kid were to ride it they would never break it because they're are not heavy enough and not rough enough. what do you think the early IBIS's had for rims. that was way back in '82 or something. weak, flimsy and heavy, steel/chrome rims. I chose to do this for a laugh not for a contest and little bikes are very light weight when they have alloy rims, bars and stem. I could even get my older brother to fabricate me an alloy frame all tricked out with magura mounts... Don't under estimate the power of the 16" bike. I would rather a steel frame more than a second hand alloy frame due to the fact aluminium gets microscopic cracks from impact (every bunny hop). these cracks will eventually hold hands. Average life span of an alloy frame is three years steel frames last until they have rusted through. In fact I just purchase a 16" kids bike this evening for $15. they were only expecting $5. There goes my frame costs now just to hack and weld and add gussets for strength and cool factor.

So basically, what your saying :

Trials wheels are strong, but pram wheels are strong enough for trials? (LOL)

Aluminium cracks, everytime you bunnyhop? (Lmao)

and children cant ride mods? (Rofl)

Good luck with that.

oh my god

shut up

YOUR TALKING SHIT

steel frames always crack quicker due to them being flexier..

fat mike snapped his twice in a year.

[Muel]

I'm just going to jump in a my ROFLcopter and come and lol in your daft n00b faces.

The guy is having some fun, spending as little money as possible, give him a break!

Please, PLEASE upload pics when done, it's gonna be a reet laugh.

[Apu]

steel frames last longer due to frame flex. Aluminium frames are stiffer meaning less give in the metal. Steel can be easily re welded with out stress on the metal. Why do you think companies like DMR use cromo? It's easier and stronger and provides a smoother ride. And yes 12" alloys would be surprisingly strong. And I never said alloy frames crack each time you bunny hop as such I said aluminium gets microscopic cracks from impact. These join up eventually and yep there goes a broken nose or cracked balls. Aluminium frames only have a 2yr warranty if you're lucky.

Yeah thanks for understanding. Who the hell thought steel frames are weaker than aluminium frames? someone clearly doesn't know a thing. Why are freestyle bmx bikes steel? and earlier trials bikes? and even good dirt jump bikes? My eldest brother is a sheet metal fabricator so working with metal is nothing new to him or me. Aluminium frames have been around since 74 or something when Kawasaki made a race bmx with triples and a twin shock back end. so please anyone don't say because aluminium frames weren't around back then.

This is just a novelty item really and somehow I don't think a 5yr old kid could go and ride a mod up a rock easily. He needs a bike that is small and agile. Easy for him/her to throw around.

[darren hughes]

i love it

[I_RIDE_ECHO!]

I had an aluminium frame! But i snaped it three times!Ihad it for about 5 months until i totalled it >>

==It might not work as i am not very good with computers.

Hey mate, im not sure if you are currently with the trials market etc. If you search ebay for a onza t-bird or t-vee ! You can pick them up for like 70 quid ?

Surely it would be better to get a bike that would fit you ? And would last longer ?

Go ahead and do it, I just don't think its a good idea ?

Yeah getting a mod would be fun but shipping costs are phenomenal to New Zealand. And clearly you didn't see the last guys video. That's what I would call ALUMINIUM. kids bikes are very robust. Being an alternative person I want an Alternative bike. not something everyone has already seen.

[Revolver]

personally i can't wait to see this 16" (or is it 12 1/2" now?) trials bike

bring on the pics/videos

I'm not quite sure why you came here, it certainly wasn't for advice it would seem. There are plenty of people on here with good knowledge of trials frames (quite obviously far better knowledge than you) - but instead of listening to them, you just dismiss their ideas assuming you are right.

The Steel vs Aluminium 'war' has been going on for years. It's much easier to create a light and strong frame out of aluminium than it is to make it out of steel. That's a fact and it's evidenced by the fact that at least 90% of trials frames sold are aluminium (probably more like 95-98%). This is when manufacturers are trying to make a lightweight yet strong frame (this is important in trials). With kids bikes, they don't really need to worry about strength (since the child isn't likely to break it), or weight. So they just make a cheap frame out of heavy hi-ten steel that is probably weaker than an aluminium frame half the weight.

I'm sure your pram wheels (that's my personal favourite bit of this thread btw ) will be made out of stainless steel and will be very heavy, and not particularly strong. Also they'll have a pretty rubbish braking surface.

There's nothing wrong with what you're doing if you think it'll be fun. Carry on. But don't believe for a second that you'll be creating anything remotely good.

P.S.

aluminium gets microscopic cracks from impact. These join up eventually and yep there goes a broken nose or cracked balls.

I have never seen anyone come to any harm from a frame snap. The most painful-looking injuries come from chain or bottom bracket snaps (which are steel by the way ).

your talking shite. trials frames are lighter than normal frames because theres less material on them. steel is heavy so the tubing on a steel trials frame has to be pretty thin to keep the weight down, making steel frames weaker. bmx's weigh how much? a lot more than a trials frame for sure

thats a t-comp though, their known for snapping easy because theres so little material on them.

and by the looks of it, you were being stupidly harsh on it.

when mike snapped his headtube off.. he scratched up his arm was a pain to watch

by the way.. his frame was steel

remember when using aluminium you have to use twice as much due to aluminium not being as string in the same quantities. The frame is only little so it won't require much metal. In fact I will guarantee you it will be lighter than any stock frame... XD. If weight was a problem I would just go ahead and TIG together an alloy frame. (still thinking about it.) any way due to the frame being small it won't flex.

[klewsh]

hahahahaha good luck with that

[Apu]

Yea thanks. It'll work.

After weighing the 16" bike I got today it happens to be less than my aluminium mountain bike. I could guarantee that once the bike will be finished it will be both strong and light with very responsive frame geometry. The bike tends to manual straight after landing a bunny hop. (the bike is bog standard at the moment) all I will really be changing on the frame/fork is the seat tube length and adding disc and v brake mounts. (disc on fork vees on frame) oh yea and the American bottom bracket shell is getting changed to European everything else is going to recycled mountain bike parts.

A mechanical Shimano (gasp) disc brake is going out front. (sourced from my scrap parts bin)

Cut and tapped Truvativ firex square tapered cranks. (sourced from my scrap parts bin)

Chosen front disc hub (sourced from my scrap parts bin)

Aluminium rims, 16 inch(yes ALUMINIUM not steel. these will be purchased new)

A long mountain bike head stem (sourced from my scrap parts bin)

Sealed VP bottom bracket

List has changed since first post due to lack of spare parts available in my scrap parts bin.

And if something breaks on the bike it isn't due to strength problems but due to the fact I am not riding smooth enough. Smooth riding is a key factor in any bicycle sport and should be considered by all. I know a guy who placed 2nd in a DH competition on a used $10 bike. All it had for brakes were horse shoes.

considering most steel stock trials frames weigh about 6 pounds and are weak i doubt it will be lighter, dob frames weigh half as much as a steel frame.

lmao you keep saying its strong enough blah blah blah and it wont break etc but now your making excuses. and that competition.. were babies racing?

i can see exactly whats guna happen, you'll make all this shit then find it was an absolute shite idea and never post on here again

[Tomm]

Anyone else thinking this MUST be a pisstake? No matching IP addresses though.

[MadManMike]

It is a tad fishy, I mean using pram wheels and stuff?

Surely you'd just save up and buy a proper bike?

[BenLeacock™]

He seems to understand what he THINKS will work? Just no one else agree's

[Apu]

I seem to understand because trial and error helped me.

Over the years I have had numerous bikes the have been solid enough for pissing about on. It's only a fart around bike. Not some $2000 mod with top quality components. I don't even think I would be able to get a mod easily here. Haven't seen a bike shop yet to display one.

Children's bikes can be very solidly built and with a few gussets here and some half decent components rescued from my scrap parts bin, it will eventually work. Remember what they used for earlier trials bikes? Haven't broken a frame yet, just a fork. And if any bike was to give way to me soon it would definitely be my "gravity bike." which is an aluminium huffy frame.

Yes the rims will hold on this little machine. I haven't buckled the stock chrome/steel ones on the bike yet and I have been pretty hard on the bike so far. Smooth riding pays off if you want parts to last.

considering most steel stock trials frames weigh about 6 pounds and are weak i doubt it will be lighter, dob frames weigh half as much as a steel frame.

It was the nationals race here in Christchurch, NZ the guy came from overseas and had no bike to race on so went and bought one second hand to have a laugh on. know one realized he was going to win, not even him.

[klewsh]

hahaha he has to be taking the piss. I done this with a standard 20" frame and it was not worth it. Now i got an adamant a3 and my riding is to times better. The two bikes just don't compare. You will become a better rider if you buy a proper bike.

I like this bit

After weighing the 16" bike I got today it happens to be less than my aluminium mountain bike.

Imagine that, a 16" childs bike weighs less than an adult 26" wheeled mountain bike.

This bit is good too

I know a guy who placed 2nd in a DH competition on a used $10 bike. All it had for brakes were horse shoes.

I can't think of anything to say other than
