Another new TQ motor: hpr40

[Calcoaster]

Something about the automatic translation (ai?) with both voices the same makes me feel as if I've just joined a cult...

I watched that segment again and the translation said the BMC is a “super light unicycle …”
No wonder it only weight 8.5kg!
Then when you bolt on the front half of the bike it will weigh more than the canyon. Or the AI translator is showing its limitations.

theoretically... You could do even better.

the lightest mass produced disc brake bikes out there weigh a bit under 6kg. Scott addict RC, Canyon Ultimate CF Evo Disc 10.0 LTD, s-works aethos, all in the 5.8 to 5.95 kg range. it’s safe to say that if there was some easy way to go way under that on a 2x road bike with disc brakes, someone would have. There are 4.x kg bikes out there but often single speed with all kinds of crazy bits and pieces.

so let’s start with 5.8. the tq hpr40 replaces the bottom bracket, which weighs 65 grams, and the di2 battery can go also, another 52 grams saved, so we’re at 5.68 if we start with a $13,000 build and remove a few redundant items. now we need to add the hpr 40 motor 1,170g and battery is 1,460g. 2.63kg, bringing the total to 8.11kg

a 17.86lb e-bike. this is lighter than most inexpensive non-electric road bikes - but of course we started with a five figure bike. can’t wait for the hpr40 to come to a wider range of bikes and in the USA. I think it’s likely the frames for these bikes will end up a bit heavier than the 600g ultra light ones, which may be where the 8.5 came from. still, low 18lb…

That's the problem with AI: You never know if it mistranslated what they actually said, let the cat out of the bag on the unicycle, or just fabricated the whole dialog. For all we know, they were really talking about the weather.

rainy and hot with a touch of squid.

(from an AI that likes The Watchmen). (apologies, feeling a little silly at breakfast this morning). (not enough coffee).

Funny story. For her 80th birthday my aunt asked if I would join her doing her favorite ride (Mt Adams loop 53miles/3500'). She rode her Pinarello with a TQ50, me my analog Emonda. She made it no problem with 40% battery capacity remaining, whereas I felt fully depleted after trying to keep up with her on her ebike! As others have mentioned the TQ was very quite (I could not hear it from a few feet away) and seem to provide a very natural assist for her. Pretty amazing.

Please tell your aunt she's my new hero. Recently did around 3,000 ft in 30 mi on my Vado SL 1 at 77 yo. Used 73% of my 320 Wh battery and still came home totally whipped.

I'm sure her bike+rider weight was considerably less than my 104 kg, but still...

I will, she will be trilled to hear that. She probably weights 50kg on a 12kg bike, so just a little lighter...
