Dirtsurf - Mount and protect using innertubes and tires

Picture of Dirtsurf - Mount and protect using innertubes and tires
Hello there, so this is my first ible, not very good at it, but  I am going to do my best.

I am a 27,brazilian applied mathematician ( no i am not a teacher, i am specialized in animal health...long story )  and for a while i have been wanting  to post a ible, and buy a dirtsurf.
Well the problem is that here we did not have dirtsruf, and importing one is was out of question, finally i came across a  guy selling a really good "generic" one in a different state and at a very reasonable price (around ($375 including shipping fee). Of course it is not the same quality (its made out of steel not aluminum), wood shape, so its way heavier but the overall quality is pretty good, 20" wheels, disc brake and all the stuff. 

So i took the guts and bought it. The main reason why i wanted one besides the fun it promised is that i am planning on transforming it to electric using a regular bike kit (crystalite or something similar) and using it to commute to work.

Being the way i am i had to upgrade it somehow!, so this ible is about how i managed to assemble it and give it a few upgrades (more to come)

Disclaimer: sorry for the bad english, its not my main lenguage, and sorry once again for the bad pics, only had my cell camera!

Olá, continuando....

O freio é aquela alavanca? você consegue descrever a "pressão" do freio? porque eu acho que no primeiro dia eu já morrer ao descer a minha rua!
Eu vi Dirtsurf para freestyle feitos com aro 16 (http://www.plunderguide.com/dirtsurfer-freestyle/). A minha intenção era a de usar como meio de transporte, pelo freio, mas não vou conseguir subir em guias, acho mais adequado Carveboard ou o Mountainboard

sim o freio é a alavanca, sendo freio a disco é regulavel mas se você fizer uma pressão a mais o negocio estanca na hora! mmuito bom o freio! Realmente a velocidade que se pode alcançar em descidas é bem grande!

O dirtsurf de uma maneira em geral não deve servir para o seu proposito pois o angulo de curvatura é maior, a velocidade também e a distancia do chão menor que o do carveboard por exemplo!

É mais uma brincadeira para downhill

Então por enquanto não vai servir para mim! Eu vou continuar procurando Mountainboard com freio, e mais pra frente talvez eu comece a praticar downhill (porque não dá pra não gostar)

I'm curious how the steering works? I know how it works on a regular skateboard but with only two wheels this must be very different.

Actualy you just have to lean over, the same as a regular skate. It as a pivoting arm that works similar to a gyroscop . The heavier the guy and the faster you go the easier and more stable it gets. This one is a bit heavy, i AM planning on building onde using aluminum with a few tweaks
We also have these on the http://velobags.com.ua

Cara vc é brasileiro tbm...isso é raro por aqui rs eu estava pensando em converter uma bike normal em um dirtsurfer,você acha que isso é possível?
lordvellos (author)  caugusto13 years ago
Possivel é sim, inclusive antes de encontrar esse cara parceiro la do sul tb tava com esboços de fazer isso, mas sinceramente desisti pois nao achei que valeria a pena, veja bem a não ser que vc seja muito bom em solda, tenha os equipamentos e saiba fazer com precisão o negocio nao dá certo.

Os custos se mostraram pouco diferente do modelo basico para o que eu queria fazer, esse que comprei já é mais top!.. para se ter ideia eu iria gastar R$300 de soldador, fora a bicicleta doadora, outros R$150 e os outros materiais como freios a disco, shape tubos para alongar, etc.

sem falar que as medidas e angulos são determinantes no processo de fabricação para o bom funcionamento, um angulo errado e o dirt se torna incontrolavel!

Com a parceria que fiz com o cara consigo trazer/enviar os modelos mais basicos por cerca de R$600 e esse modelo mais top por volta dosR$800.

Se tiver interesse me avisa por mp

So uma dica, pergunte em ingles tb, sua duvida tb pode ser a de outros e ajudar!

Yes it is possible, before finding this guy in the south i made sketches to do this, but honestly i gave up because I thought it wouldnt be worth it, you see unless you are very good at soldering, have the equipment and to know accurately do the business it does not work out.

The costs proved little different from the basic model for what I wanted to do, the one I bought is a more top model! .. to get an idea I would spend R$ 300 welder, the bike donor, other R$ 150 and other materials such as disc brakes, shape tubes to stretch the frame, etc..

Not to mention that the measurements and angles are crucial in the manufacturing process for the proper functioning, a wrong angle and the dirt becomes uncontrollable!

With the partnership with the guy I can now bring / send the more basic models for about R$ 600 and more top models around R$ 800.

If you are interested let me know by pm

just a tip, also ask questions in english, it may help others too!

i have been wanting to make one of those for ages and now i know the name, so that will help:):):):)):):):)):):):):):):):):):):):)

Cool i could help, you know the original one is patent rigth? But i was able to get the patent requirement with all the info and specs, maybe i could send it to you. I am not in any kind recommending anyone to copy it for profit use, i only have it because it was impossible for me to buy one and i needed the spec to properly see if my project was feasonable. If you need anything let me know
ok, how did you get the patent?
lordvellos (author)  The nerdling3 years ago
Actually i dont remember i have it for over an year, but i think i just google it. it was a downloadeable pdf! it has all the main info and measures!

if you want i think i could send it over e-mail.
ok, that would be good
just pm me ind il give you my email

i been looking in ways to make my own dirt surfer.. and convert it into an electric one.. can you put and instructable in how you made it electric?
lordvellos (author)  mstyle1833 years ago
At least for now it is not electric yet, i am testing the specs of the plain board and its usability for day to day use and of course learning to ride it. I am taking notes for further improvements of the board and trying to buy an electric kit (way to expensive in brazil). The protection was the first part, brakes, speedometer(bike pc) ,mudguards, footstraps, carry bag and all the electric mods are to come. The final version will be electric, day to day use friendly, ligthweigth (probably aircraft graded alumminum), easy to pack and fast. I am waiting some parts to arrive as well as the protection for my body.. This thing is fast downhill ! As soon as i have more news i will post them. If yo uh need anything just ask!
