Electric Bike Conversion Kit

Karl Gesslein / December 23, 2015 There has been a near-mutiny of BBS02 owners (rioting in the streets) who have been disgruntled that their BBS02 units have shipped either without any grease in the secondary reduction gears or with the ill-suited white lithium grease in the secondary reduction gears. Both setups are not appropriate and will cause premature secondary pinion destruction and wear as well as making your drive unit much louder than it should be. A properly greased BBS02 running at full tilt should sound as loud as a large handheld drill and no louder. “What did you say?” *yelling* – “I...

Karl Gesslein / July 24, 2015 Paul from em3ev threw in a free Giant Green Button with our last $4,200 order so I could write a review for it because I was too cheap to spend $6 on one. It took me several weeks to get around mounting it to a build and try it but I finally did and was under-whelmed. This button is designed as temporary PAS cutout for the BBS02 so you can shift without grinding the gears and chain together. What I keep calling the Giant Green Button is actually pretty tiny.   Installation takes all of 5 minutes, you...

One of the first things that most people think when they open up their BBS02 kit is they take one look at the handbrakes and are left wondering how such a nice kit comes with such crappy brakes. Hydraulic brakes are the defacto standard for most people who ride ebikes in the US which turns a 30 minutes install job into several hours as people scratch their heads wondering how to install the ebrakes on a hydraulic braking system. Here are some options that will help you through. Perfect for a scooter or motorcycle, but a little much for a bicycle. Option 1)...

Karl Gesslein / June 7, 2015 Heat is the enemy. A $2 thermometer can save your $80 controller and a lot of headaches. Electric motors can often take far more power put through them than their nominal rating, but over time the heat will build up and cause all sorts of problems. Mosfets can blow, phase wire insulation can melt, windings can fuse together. When the motor starts being under high torque load and the RPM speed is slow the electricity flowing through the windings mostly turns into waste heat. The best way to keep your BBS02 from blowing is to mount...
