    SURLY KRAMPUS 29+ BBS02 750W Nuvinci N360 Project Rationale

    Hi Steve, well, I tried in vain to get one shipped to Europe but no chance from outside the US :( It was my 1st choice for a 1st E-Fat conversion project (73mm BB and 135mm rear axle) and it looked decent enough and Karl Gesslein has so much (well documented) fun with it...

    So just how far apart ARE the cranks?

    OK, get your intention... and a HaiBike is not the one for your offroad needs?

    The Ogre has landed ...

    Hi John, took at peek at your build. I wonderd why the housing of the BaFang does not rest flush against the down tube? With higher torque it may well work it's way up there I guess... Regarding an extra chain in the saddle bag: could a mini chain tool and a link save some weigt? What other...

    So just how far apart ARE the cranks?

    What's the Problem? A Giant FS MTB has a BB no larger than 73mm I suppose, it's not a fatikbe is it? So what are you waiting for? Go-Coo

    So just how far apart ARE the cranks?

    Hi MLB, here are some measurements at last: the inner distance of the (generic) crank to crank is 16+ cm (cranks were just loosely fitted on the axle). As the BaFang has quite an offset to the right when mounted on my 73mm BB I partially adjusted this with another left crank that reaches a...

    SURLY KRAMPUS 29+ BBS02 750W Nuvinci N360 Project Rationale

    Hi guys, slowly getting somewhere though I'm still playing the waiting game... I ordered the battery a week ago ;( 2nd preliminary setup to check ergonomics and the ride feel (only a few circles around the house). Well, it feels ... hefty! Sure asks for some extra power. So long, Go-Coo

    Cellphones, pedal power stroke and Power Assist Levels

    Hi Mike, this is close to rocket science! Am afraid that I'm no intellectual match here... did you post this over @ Endless-sphere yet? You might get more qualified feedback there... My (mechanical) viewpoint: Cyclists try for some time to both stretch and/or "fatten their peanuts" with...

    SURLY KRAMPUS 29+ BBS02 750W Nuvinci N360 Project Rationale

    Hi guys! Beware: If you are under 35+ or prefer weight weenie speed machines running on tarmac read no further. If you are 35+ and love to go where you imagine no one has ever went b4 then read on: Why (Semi-) Fat? I just hate to get stuck in the muck! So I've been eyeing fatbikes since...

    What rear hub to use with 8fun

    Hi wa5, I've been riding the Alfine8 for quite about 3 years without a motor. No issues so far but I do take care NOT to shift under load, though it happens from t to t. If you use either a break-sensor to shut down the motor when you shift or use the green button option I think the Alfine...

    My Surly troll half fat e bike

    Hi Spotty, Your girlfriend's bike (Karate Monkey is it?) is just as awesome as your Troll, Wow! You must love her at least as much as your own bike ;) Thanks for all the great info and picks. I got to admit that my understanding circuits got blown though... The idea of having a 2nd energy...

    My Surly troll half fat e bike

    Hi Spotty, This is my current nonmotorized all-for-one bike btw, overall not unsimilar to your 1/2 Troll: As you inspired me to go a bit more low-profile I swapped the Table Top to the rear and put a smooth Crazy Bob in front. It's a folding bike with an eccentric BB. Used to be a the...

    My Surly troll half fat e bike

    Hi Spotty, your recent mods sure look a lot more sporty. Your set-up made me swap some tires here, too. My Krampus frame will probably need to be shipped from the UK, sold out here... There are some sites you'd probably enjoy reading...

    My Surly troll half fat e bike

    Hi Spotty, Thanks for easing my mind on the single lockring and Nuvinci performance. You really managed to align the chainline PERFECTLY! Hope I'll do... A picture of the whole bike in it's current incarnation would be cool. Still wonder how you manage to go so low profile? I have found a...

    My Surly troll half fat e bike

    Hi Spotty, thanks for sharing, awesome build, really! It looks a bit tame and old-school (somewhat like my current non-e-bike) but with the new 750W Bafang it's sure a blast on the road. You must have earned a lot of disconcerted looks zipping bye ;) Am planning a similar project, same...
