    No problem - please add me to your interest list. In the meantime I will try to get smarter on available friction motors and the battery options. Thanks.

    Anybody ride with a BBS02 mostly unpowered?

    You're probably right about this. The more I try to envision it, a BBS02 on a bike that will be powered 10-20% of the time feels like a mistake. I was leaning toward a lightweight geared hub, but: I took Grantmac's advice and checked out the Kepler, and I'm sold on the idea of trying this...

    Kepler Bottom Bracket Friction Drive For Sale (Finally)

    Hi Kepler, I am impressed with your work, and am interested in purchasing one of your kits. I plan to install on my Novara Mazama. It seems my BB to tire distance is within range, see picture. My plan is to ride mostly unassisted, but for longer rides I plan to take a battery with me, in a...

    Anybody ride with a BBS02 mostly unpowered?

    Thank you for the responses. I am assuming the Kepler drive would be noisy/"buzzy", and that would be a deal breaker for me. If this is not the case please reply. The Bafang G310 looks like an attractive option. We have some hills, of course, but they are not ridiculous. The hub itself...

    Anybody ride with a BBS02 mostly unpowered?

    I am curious whether anyone here rides a bike with a recent BBS02B, but uses it mostly unpowered. I'm thinking about fitting this on a bike that I would ride 80-90% of the time without a battery. My normal commute is short, and I would only attach a battery when I'm going long distances. I'm...

    First build (BBSHD) - any advice?

    I would agree about the gearsensor being essential. I also read mixed reviews, and was on the fence about it. I rode for a week or two without the gearsensor (before I got around to installing it). I still haven't installed my brake cutoffs, so I had to stop pedaling, wait for the motor to...

    First build (BBSHD/Boris X9), some battery questions

    Thanks induna/Drunkskunk for explaining that. I've read a bit more and answered a few of my original questions. Here's a summary, in case it will help other noobs: Luna and em3ev are both very reputable 18650 battery pack vendors. They both sell similar batteries for 48V motors. Luna...
