Hello,
im currently building a slow puller with a setup i worked on over the years. This one i wanto to present here uses a scorpion HK 5020 Motor , a ASI BAC 500 controller and a modified Neugart PLE 60 first reduction and a 219 chain second redction to get an overall reduction of 41,85. In the following days i will post something like a build thread but i fear im not very good at dokumenting..

Here i have some pictures of the hub which has been build. Its made of steel and steel flanges which are mig brazed together. The freewheel side is made such that a ratched system from a dt swiss hub will fit into. The other side is just a long BSA thread to accommodate the freewheeling sprocket ,support bearing and disc adaptor. The disc adaptor and the freewheel where tightened together during operation.
The Motor and Neugart gearbox are held by an aluminium construction which includes some vibrational decoupling to reduce noise propagation.
The wheel is 29 with a 2.6 tire mounted

Some of the parts shown above had been driven for more than 2 years now in all weather conditions . So they are used ;)
