This is my thread documenting the build up of a SIKK Bicycles SS Aluminum Fat Tire Cruiser. This is my first build ever and this is probably the worst bike anyone could pick for their first build. Its been challenging but lots of fun. The first picture you see is the bike in its stock form. It has a Sturmey 3sd IGH, tapered head tube, 26X4 Sandstorm Tires and disc brakes.
For the first set of mods I removed the handlebars, stem and seat. They were replaced with Race Face stem and handlebars and Bontrager seat. The bike looks like its uncomfortable but actually its not. I rode it in the stage one modified form on a 15 mile ride and it was fine.
Next was the Bafang BBSHD kit. This is where I ran into problems. From my measurements it looked like the motor would fit perfectly. I had to get the extra fat version of the kit and felt it would install with no problems. Famous last words. What I didn't know until I tried to install the motor is the bottom bracket shell is not the same diameter all the way through. It took me two days of "porting" to get the motor to slide in with no problems. Finally it fit with no issues. The only minor problem I have is the bike originally came with a chain guard. One of the tabs is in the way of the motor and wont let me rotate it up any closer to the frame. I may eventually break down and remove the tab but for now I'm leaving it alone.
The next issue that came up is the chain line is way off. I purchased Luna's Eclipse chain ring and the spacer which should fix the problem. I'll also need a longer and stronger chain since the Luna chain ring is larger than the stock one.
Next step was hooking up all the electronics. I also tried to hide all the wires the best I could. I ordered from Amazon a Mucky Nutz gut fender to mount on the bottom tube of the frame. This will hide the wire coming from the motor up to the handlebars. Again from Amazon I bought a set of neoprene wire covers. These are actually used for hiding audio wires but will work in this application as well. I'll be able to bundle the wires inside the cover and make it look like there are only three large wires going to the bars. I'm still waiting on these items to come in so the jury is out on how well this will work.
I had a custom battery and case made for the bike. The whole assembly measures 11X4X3 and will mount in front of the rear wheel. I'm still waiting for the case to come in but I included pics of the battery. Its specs are 52V and 17AH.
For now the build is on hold until I get the parts I've ordered but hope to have it completed by next weekend. Stay tuned for more updates..................
