So I bought a Dutch Fat Bike from Switzz Bikes!
Fat 8.1 specs:
Tires: Kenda Juggernaut Sport 26″x4.00
Frame: Aluminium 6061
Disc Brakes: Tektro Aquila Mechanical Disc
Gears: 8 Speed Shimano Clarius
Chain: KMC -72
Cassette: 8 Speed HG41
Dropout / HUB spacing / Axel for rear wheel: 197mm and Switzz says I need 220mm!
Bracket for midmotor: 120mm
So I bought the Fatbike kit from www.future-bike.it
500 W option with 120mm bracket
Protection cage for motor
48V 17Ah battery in bottle form which can be removed
Race Control Display type VLCD6
Metal Gearings as standard
42T with 10mm offset (installed this one)
32T race torque thing I will never use...
Maxspeed is around 40km/h, than I pedal so fast the motor stops assisting...
I can really climb hard with this bike! So far one big LOVE for this built!
I did a test ride on a 18km technical, steep short climbing MTB track in The Netherlands and it was awesome!
Installation took some time to figure it all out and some issues:
-Battery could only be mounted upside down on two M5 bolts (so far no problems, but double check to lock the battery before riding)
-Speedsensor did not work but found some strong neodymium magnets which fixed the distance problem
-Motor would rest on a part sticking out from the motor on the left so I bought a wedge to fit in the middle
-The bolt which should fit on top did not fit because of the big diameter of my frame. I just did not use it....
