SPECBIKE TECHNICS nojapyörä

ViestiKirjoittaja Specbike » 19 Elo 2017, 14:47

Greetings to all!
My name is Vladimir, I'm from Latvia, many of you I met at a competition in Nokia. I noticed that many people were interested in my seat. I'm ready to tell more about it.
The seat is made in 2013 from ordinary steel 1mm, cut with a laser and welded, everything is simple. Thanks to the minimal form and a lot of holes, the seat is light enough. With brackets 1.9kg.
Seat mat also very interesting.
If you will be interested I can give drawings for laser cutting.

Welcome to Nojapyöräfoorumi, Vladimir. :)

Very intresting seat in deed. Laser cutting gives a lot of freedom for designer.
One question i have. Why did you choose steel even if your bike is aluminum? Was it the reason the impossibility to weld aluminum sheet thin enough.

Kuva

I am intrested to build a integrated seat(able) bike frame, which can use a little boot for tools, spare tires and other necessaritys.
Frame-seat should be thin aluminum sheet which is very difficult to weld. Maybe seams should be riveted. By laser cutted parts it might be possible but can grow too heavy. :roll:

The frame of my bicycle is also made of steel.
With aluminum, there are many problems: strong aluminum does not bend and you have a lot of welding, soft aluminum does not hold loads, thin aluminum is hard to weld and thick has a lot of weight.
As a result: many problems and little benefit.

Yes, of course. I messed up yours and Reinis's bikes. :oops:
You are talking about aluminum just like jooseha here. And you are right. Aluminum is not for DIY projects.

and here it is!
a lot of difficulties with the adaptation of fastening, wires and programming behind and now I can say: the motor works very nicely, guesses your desires and helps smoothly.

That full suspension trike is really interesting.

What's the maximum load (driver & luggage included)? The rear rack looks a little flimsy.

Is the height of the front suspension adjustable at all? Looks a little high, with light load in your summer photos in other thread :)

How's that normal fiberglass seat without any side supports? No mesh seat option? My experience with trikes is that it's good to have some side support on the seat. Then again it may be just me, I tend to roll every trike I ride :D

rider weight 120 kg and a new luggage up to 50 kg. for frame and rack is a guarantee.

The front suspension is designed for shock absorbers 165x35, you can adjust only the harshness of springs or air pressure if you use air springs (option)

the seat is a very individual question, we can install a seat of any manufacturer and with a mesh too, or sell a trike without a seat but with brackets. You can try the trike in Riga at any time. Welcome.

Excellent video.

Yeah, the seat choice is a matter of taste. It would be interesting to hear how you and your friends have liked a narrow fiberglass seat like in your photos on a trike?

I have a slight case of trike fewer at the moment :) My wife bought herself a new one (fully suspended ICE) and I have been having fun with her Azub T-Tris. It's a great machine but lacks suspension. Hence my interest in your design. Who knows whether the disease will cure by next spring or not :)

we started from the beginning of this year and already have more than 30 customers in Germany, all with standard seating.
you can study the discussion about my trike on the German forum.

ICE and AZUB great machine with a high price and for intelligent road. :D
if you need a machine for ruthless use - welcome to me. :D
(please do not postpone until the spring, next year I'll have a price increase and queue before the summer season)

I did send some specific questions about customization using the contact form on specbiketehnics.com.

For others interested in this trike I'll repeat some of them here:

Is there a folding mechanism option? There are some photos in various webpages that suggest at least a prototype of a folding mechanism exists.

What brake, gear etc. options can you offer installed from the factory? Of course you can order a frame kit or a basic model and then switch components yourself, but not everyone is interested in tinkering.

Tässä saattoi nyt käydä sillä lailla että tommonen täysjousitettu comfort trike on tulossa Porvooseen kunhan saavat kasattua :mrgreen: Availen varmaan oman ketjun sitten kun pyörä on kotona :)
