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. If I don't sell it,...

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...

Archer D1X Wireless gear shifter

I was looking at electronic systems, and came across this wireless gear shifter, which works across any type of derailleur system https://www.bikemag.com/gear/tested-archer-components-d1x/. I like the idea of limited cables, particularly where I have had a battery box cut and welded into a frame, an...

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...

Re: Aluminium vs steel contraction when frozen

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

Hey guys, Due to a loose screw on my disc brake, I've managed to yank out my phase/hall wires from my Edge motor. Anyone have tips for pulling apart the Edge motor so I can go in and try to repair the damage? I've taken out the screws, pulled apart the motor part of the way and now the edge of the ...

Universal charger?

Hi,
is the charger shown below universal? 110v is marked in red, but the similar chargers I can see on the internet are noted as 110v / 220v.
thanks
