Norco Atomik with BBSHD

At long last I got around to finishing this build - a 2005/2006 Norco Aline/ Atomik, with a battery box cut and welded by Samd. Battery is 52v 21ah 14s battery, BBSHD. Boxxer World Cup forks, Fox rear shock, Lekkie bling ring. Test ride this morning - bike is really lightweight, very smooth. The rea...

Re: Townie host bike rethought.

A dropper seatpost would fix the problem but I use suspension seatposts, don't know if there is a dropper post with suspension. When you get too old, shock to the spine is a significant risk. Well, ebike planning is part of the fun. I found this dropper post with suspension https://www.pnwcomponent...

Re: Townie host bike rethought.

unless I am misreading something, in which case I apologize - what about a dropper seatpost for the Trek 920? I have recently fitted these to 2 of my ebikes (and one non-powered), they are such a pleasure to use - save my knees, while still allowing to drop whenever I need

Re: How good are the BikeE recumbent bikes at high power / high speed?

I have a Rams Stratus XP (26 inch wheels) I haven’t electrified yet, but will at some stage in the future. It is ridiculously easy to cruise along at high speed with minimal effort. I love the bike’s efficiency.

Re: E-S LMX 64 Bike Owners

Could owners (or LMx) not go 18T front cog, and 50% larger rear cog? Visually, it would mean a lot larger rear, I realise.

When I moved from a 12T to an 18T on an LR kit - it was a lot quieter at high rpm

Re: Stealth FUTR owners builds and pics

Nice setup Lash. I have the same carrier, but for double motorbikes. https://www.discountramps.com/double-motorcycle-carrier/p/AMC-600-2/ the only issue is that the main beam is so heavy, I never use it, as it is just too much of a pain to get out of a store and carry downstairs.

Re: Donor for tall guys

is the $700 for the bike, or the bike, motor, controller and battery? You may need to travel a bit to get something decent. https://sfbay.craigslist.org/nby/bik/d/santa-rosa-surly-karate-monkey-large/6898134435.html https://sfbay.craigslist.org/nby/bik/d/novato-santa-cruz-blur-xl-ritchey-wcs/6890246...

Re: Stealth FUTR owners builds and pics

I am about to put a Edge 1500W motor with FF and hubsinks on a Beta frame. Previously, I was running a LR kit, but I will use the LR kit on a future build, possibly with a left hand belt drive. With the edge motor, I now need to think about the cassette. I tried a 7 speed freewheel, but it projected...

Re: Aluminium vs steel contraction when frozen

Honestly, it's well known brain-teaser as to whether the hole in a ring gets bigger or smaller when it's heated. The trick is to mentally uncoil the ring into a rod. When you heat a rod it obviously gets much longer than it does thicker and if re-bent into a ring it would have both a larger outside...

the above replies are exactly what I thought, logically - until my wife gave her opinion which confused the hell out of me.... Her view is that when metal expands, all the metal will get bigger - so the hole gets smaller. When the metal freezes, all the metal shrinks, so the hole gets bigger. My min...

Aluminium vs steel contraction when frozen

So, I have a bearing outer ring stuck in a aluminium frame (the swingarm). The bearing has broken, leaving only the outer ring wedged in.

If I put the the swing arm in a freezer - would the aluminium extra contraction make it easy to extract? How brittle would the aluminium become if frozen?

Thanks
