    Very nice ebike! Your Rohloff makes me jealous. I want to upgrade to one someday, but will have to sell off one of my ebikes to do it. Just got my Surly ECR pedaling today, but the left crank arm is too close to the rear stay for comfort. How is your left crank arm clearance on the Ogre?

    That looks like a BBSHD 1000W mid-drive to me, not a BBS02 750W. Typo or did you really think it was a BBS02?

    I like your thought regarding weekend overnight trips. Hoping to do a few on my ECR, possibly fishing weekends in the eastern Seirras.

    The Rohloff hub is a dream. Heavy, but the shifting is really solid, smooth, and quiet, with tremendous gear range.

    Hi Pedal AZ. I’m very impressed with your first build project. I’v been thinking about a chromoly 29er MTB for my next build and your build is certainly providing inspiration. Probably knowing the answer, but why did you choose the molly frame for the doner bike. Also Interesting front fork set. No suspension up front.? Looks like quality and well engineered. I’d like to hear how it all works when you get some miles under the tyres in AZ.

    Surly Ogre with Luna/Bafang 750w mid drive

    My first eBike, set up for riding forest roads and less technical trails around Prescott, AZ. Tons of hills here, where the climbing power will be handy. I may attempt some out and back overnights, hanging some storage on this very utilitarian frameset.

    First test ride delivered over 40 mph on flats, over 20 on a steep paved climb, and fun on singletrack. The throttle is too sensitive, when power comes on suddenly, or by mistake, riding in rock gardens and technical terrain, when the finesse of pedal power is preferable.
