    Another new TQ motor: hpr40

    yes. insane!!! the lightest mainstream road bike frame on the market is the s-works aethos at 1.3lb for the frame. a fairly aggressive high end build (dura ace, one piece cockpit, light and shallow wheels etc) is around 13.5lb. even if the frame didn’t have to get heavier (have to imagine it...

    Another new TQ motor: hpr40

    given the whole drive system incl battery weighs only 6lb… it ought to be possible to build a 19-20lb e-bike with this setup. have to use some weight weenie components for sure but why not 😇 it will be very interesting to see if the US version is 32 or 45 kph. if there’s some technical reason...

    moving things can make funny sounds... for a little while i had a VERY annoying metronome like "click" every time the pedals went around on my acoustic bike. bottom bracket, chainring, chainring bolts, checked and rechecked and lubed and torqued. one day i took the pedals off, don't know why...

    not for road bikes tho, we'll see if the next generation goes that way. everyone i know who has a 12 speed di2 road bike strongly prefers the lighter derailleurs with 6 months of battery life. the integrated e-bike power is great, i would totally do that on my di2 e-bike.

    i’ve just always preferred the choices shimano makes. the ergonomics and aesthetics fit me better, and i really, really dislike the small batteries attached to the derailleurs that SRAM does. they are ugly and need to be charged too often. shimano puts a battery in the seat tube and wires the...

    another very nice looking new bike with the HPR40, this one a ridley gravel bike. $9k GBP in GRX di2

    Another new TQ motor: hpr40

    yeah, but comparing sale prices to not isn't really apples to apples. bikes often go on sale, and the current Rival AXS Nytro Gravel bike is $7,800 MRSP, the tesoro carbon 1 is $6,600 with some similar GX eagle bits (not really following why they mix up the parts so much on SRAM groups!) but is...

    would be awfully surprising if there wasn’t enough juice in the lighting wiring, given that the 67i has a pretty small 3.8v 3100mah battery. you’d need to check the voltage of the light output (probably 5v?), see if the device runs from power at the USB port (many don’t) and if not devise a...

    i don’t like SRAM anything, but the pricing is pretty comparable to what others do in the space, the $7850 skitch has the same level SRAM drivetrain as the $8999 creo 2, right?

    Another new TQ motor: hpr40

    i think you'd really like the skitch. 31lb, 10-50 cassette, fazua 60, 400ish wh battery, 31lb! hopefully your SL will never need a replacement, but ride one of these if you have a chance :) it's in stock at lots of stores here in the bay, i'm sure it's easy to find in SD also.

    of course they do :D with modern mid drives in the low 80s, even a big improvement (say 80 to 85% - a quarter less wasted energy!) wouldn’t make much difference. of course any increase is good.

    Another new TQ motor: hpr40

    the range issue really comes down to 1) efficiency - any modern mid drive should be about the same 2) if going flat … speed. assist past 17 or 18 mph is going to eat watts FAST 3) if going uphill, rider weight and power. unfortunately for a 200lb total package, 5lb of bike weight isn’t...

    Another new TQ motor: hpr40

    a really, really nicely integrated system. drivetrain and lights powered by the internal battery, options for expansion, no big displays on the top tube or bars! odd that the review didn’t mention the overrun issues others have, and the end result of the very different strategy for crank /...

    what do you mean “pop?” if you’re rolling down hill and the pedals aren’t turning and it makes a loud sound, the number of places it could be coming from are very limited. does it also do it with the electronics and motor completely turned off? that would limit it even more, basically only the...

    Another new TQ motor: hpr40

    it doesn’t feel much different than any carbon road bike with similar geometry, I’m sure. My addict eRide weighs about 24lb, and descends a bit more solidly than my 14lb aethos. they have the same tires, similar wheels (a bit deeper and heavier on the scott), the same drivetrain and gearing, and...

    new discbrakes for Spesh

    I am not sure this collab will ever get past MTB. I think it’s even downhill only right now? they look crazy heavy.

    I left a small bag with an iPad in it at a park once. realized about 10 min later, was on my commuter hub drive. Rode back quickly, gone. find my showed it moving down a nearby street slowly. rode there, didn’t see anyone. looked harder, saw an elderly chinese American lady. approached her...

    sorry, mixed up the average listed (which is microamps) and the peak (which is milli) still won’t add up to anything meaningful for a bike battery!

    we aren't talking about leaving lights on though, it's just an illustration of how much power a battery really has. a visible light is way way more power than an idle BLE SOC. tiny, tiny, tiny amounts of power. 15 MILLIONTHS of an amp at peak, 1 millionth average, probably around 3V. 3V x 1...
