A mountain bike is great. Four mountain bikes in one set? Even better!
There are many great brick mountain bikes out there, but I decided to
make my own as I wanted to have some adjustable features. In the end I
managed to have the following on this bike:
- adustable seat height and inclination;
- adjustable stem height;
- front and rear brake discs;
- option for hardtail or full suspension (1 hardtail model + 3 full suspension models = 4in1);
- front fork can make full turn;
- GPS/phone mount on the stem;
- water bottle and cage;
- front and rear lights.
The instructions include options for 4 models (4in1): 1
hardtail model (no rear suspension) and 3 full suspension models. The
fork assembly is the same for the 4 models. The 3 full suspension models
are all four-bar linkages, or Horst-link, but have different types of
rear suspension rocker. The frame geometry is very similar for all 3
full suspension models, with small variations of length of seat stay and
chain stay. The connection between the seat stay and chain stay is a
bit different from other bike designs out there, and that is how I
managed to include the rear brake disc.
This model is based mostly on sets 42063 and 42107, plus a few parts.
Now go outside and ride a bike safely!
