i take no responsabilities on that ! thank you dude! -

Thats crazy o.o -
my advice would be: focus only on the geometry and weight distribution of the model. Once you get something that can go at slow speed without falling down you start adding features. take this as an example, it only has the basic angle and pivot offset and it is really stable at slow speeds, you litterally push it gently and it will keep going straight. Try finding the right angle and wheelbase that gives the bike the behaviour you're looking for and then you add all the rest on top of that trying to keep the same setup as much as you can. Of course trying to keep the bike as specular on its forward axis is quite relevant for the weight distribution but the lower down you got differences the leatest impact they will have on the bike. Take the Baja bike as an example, it goes straight even tho the servo and the L motor have different weights, but they are placed at the bottom of the chassis where it doesn't affect the balance too much.

I was wondering if the video was slowed down or if you just had some crazy good handling on it, turns out you are a really good pilot lol -
Hey guys! Awesome to see that you're having fun as much as i do with bikes :) I've got more bikes coming in a while, still need to do tweaks here and there but what i can tell you if you wanna start experimenting with big wheels you can go with an XL motor, it's better centered than the others and it has enough torque to make the bike run. On these two i'm using a chain that goes from the large gear to the second smallest one (sorry i have no idea on how many teeth they have)

We should indeed! Ive done a lot of testing i can share many tricks with you guys and maybe some engineer can explain us why stuff works the way it does :) -

Ill dm you the 3d model ive made to render my images :) btw great job on the improvements! The golden rims look sick -

Hey dude thats awesome to hear! Shoot a video of it i wanna see it :) i love your design it looks better than mine :D -

the futuristic wheels work really good to be honest! the only reason why i preferred the new ones over those is that they are slightly bigger so the bike goes a little faster -

hey guys! so: - the 81.6 dont fit and you will have to widen the chassis one more stud (but i might do it for you one of these days) - it works with standard PF lithium battery and the steering doesnt get too compromised. The only problem would be the range and the speed that will make it go like the driver was drunk :D try building this one if you don't have the new wheels, it was the original model i made a while a go but i wasn't too happy with it, it was working really good but it was still bulky here and there, like the gear rack part, that sucks big time, the new one is so much cleaner :) @amorti that is cool dude! even tho i believe you dont really need to reinforce it that much, i never had the gear skipping, nor there nor on the gear rack:) -

thank you dude! yeah those tires are awesome yeah dude definitely try it out! it's really simple to control, you can use the old futuristic wheels as well they fit :) i've never seen that motor! that's cool actually! -
Hello everyone! I was wondering if it was possible making a bike that was fun to drive around while keeping it low price so i came up with this: it's a baja bike, it runs on an L motor geared up 2:1 and like the other bikes i've been making it shares the same principle to keep it upright. These new tires are awesome, they have an amazing grip and the rounded shape makes em really good for motorbikes! I hope you'll like it, here are some pics and the video i shot :)

Dude that looks so good :) have you tried it already? I've got a new bike ill share today or tomorrow that is way cheaper than that one but fun and relaxing to drive around :) -

I do really like your color scheme and the long panel too! Too bad that those big wheels won't fit in the RC motor unless you offset it on the side, so yeah great choice getting the old ones, they grip way better too! adding the pins to dampen the spring is a good idea, the only reason why i didn't use them is that i didn't like them sticking out :P It's awesome anyway, we definitely need more bikes in our builders community :D -

piterx replied to piterx's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I did indeed :P this will be the bike in my next video one of these days It's more manouverable than the other due to its lower center of gravity, those tires definitely grip better and are more stable, so if you find em for cheap definitely get them! The headshakes are something i havent managed to figure out yet, i belive the shock absorber on the back being too soft could be the cause -

First of all, thanks to all you guys for your nice words :) I made a couple of renders to help you out i hope they will be enough! if not i can render some more! https://ibb.co/Yc98gcY https://ibb.co/PYjHM8S Those tires are too big to fit on that unless you extend it a little bit more adding a 1:2 reduction maybe as well. I've done dozens of tests and the oldschool ones perform way better for grip and they seem to be the perfect radius to couple with the RC motor to get the maximum performances out of it. The only downside is that you'll get trigger happy with the ludicrous mode and eat through them quite quickly :D I strongly reccomend using it on smooth surfaces! I've got other 4 different bikes to show you guys all the tests i've done, they all work and they are all different :) soon i will post more! -
Hi there :) Apparently there was a bike contest i totally missed! I've kept myself really busy building bikes lately, this is the fastest one i've built so far, probably the fastest ever built i guess? It's really simple, RC motor, buwizz used as a weight and that's pretty much it :) It's also really really easy to control I got also another one that shares a lot of features with this one that I will publish as soon as the lockdown ends and i can go shoot a video of it. I hope you'll like it!
