EDIT 07/25 Received email from TQ senior tech with accurate info. See post 130 in this thread for details but all is well with the hpr40 in no-assist mode] Same here. I emailed TQ back asking for specifics on the hpr40 no-assist limitations. I’ll post here if I hear back. In the meantime my...

[EDIT 07/25 Received email from TQ senior tech with accurate info. See post 130 in this thread for details but all is well with the hpr40 in no-assist mode] I just got a response from TQ to an email question I had sent them in April that included some rather disappointing news about the Hpr40...

Yeah, I’m questioning the accuracy of the reporting of the BMC weight. The recently released non powered top tier team machine is 6.6 kg (BMC website number) and the hpr40 motor, battery and cables are claimed to weigh 2.7 kg. That makes 9.3kg or 20.46 lb. I’m thinking the Prototype ebike either...

BMC has a Teammachine prototype using the hpr40 that weighs 8.5 kg (18.7 lb). That’s got to be getting close to the minimum for an e-assist bike! Scroll to the end of the video for the BMC

I think we will be seeing more discounted hpr50 bikes. From what I’ve read, TQ is going to concentrate on their two newer motors, the hpr60 and the hpr40. The U.S. trek site now shows their domane+slr 9 and 7 as having the hpr60. They’re using the same 360wh battery as the 50 so it’s probably a...

Could be a bad spoke or cracked/stripped nipple. That would be an easy fix and should be able to isolate it by flexing all the spokes. Swapping another wheel in would be a quick way to narrow it down too.

Keep in mind that the predicted range is based on the European rules limiting assist speed to 15.5mph. The reviews point out that the bikes are intended for serious road bikers who will be riding above this speed except when climbing or maybe encountering big headwinds. If these come to the U.S...

I just noticed trek is starting to use the hpr60 on their domane+ slr models, at least on the U.S. site. I wonder if they’ll eventually have both the 40 and the 60 as options.

They moved forward with a better product. I think trek and fazua still support the older gen systems, but who knows for how long.

I’ve read multiple people who have moved from the earlier treks with fazua to the newer TQ versions say that TQ is a huge improvement. More reliable, quieter, smoother power delivery, overall better performance.

Just announced, and Canyon’s high end TQ hpr40 ebike weighs under 22 lbs. Interesting direction for TQ: lower power, smaller battery, no top tube ebike display, hidden assist level buttons, all but invisible. 200 Watts (nominal and peak) and 40nm torque. They’re going for the ultimate roadbike...

You sure it’s not a rear brake issue or a chain/ gear issue? Take the rear wheel off and you’ll isolate the motor to test it.

Anyone have experience with the 5 10 trailcross lt shoe? Looking for reviews from users on how it would work for road riding: some stiffness, grip to pedals, comfort, weight and feel, etc. Or any other recommendation for road riding in dry climate. Looking for lightweight, fairly stiff sole...

Thanks for the input. I’ll read up on those three pedal choices.

Stefan, Due to a costly mishap I’m exploring going from SPD cleats and shoes to flat pedals/shoes. I looked into your 5 10 Freerider Pro recommendation and they look good but heavier and more bulky than I need. I only ride on the road so I’d like something light weight and don’t need aggressive...

How do you like the Fox shoes? Im starting to look at flat shoes and pedals for road riding. Are there light weight shoes and pedals out there that work well as a replacement for clipless? for the last few decades I’ve used SPD pedals with the least aggressive mt. Bike shoes for the road. I just...

Yeah, they claim to have resolved the thermal throttling issues. The hpr60 motor looks the same except it has fins on the bottom for cooling. I have never had a problem with my HPR50 but very rarely use more that half its available power output.

Yes, it varied from 58 to 69 percent depending on power. Seemed to be best at around 200-300 watts. It’s a little confusing because they talk about electrical power as an output so I assume that’s battery power output, which I would call motor electrical input. And they explain how peak power...

I came across this site that tests e-bike motors. Their most comprehensive test is of the TQ HPR50 and it’s pretty interesting. Their most comprehensive tests were all done at the highest setting and thermal throttling was an issue that the test shows well. They tested with 150 watts rider...

I have a BMC roadmachine 01 Amp X two. It uses the hpr50 system and a typical ride for me is 25-45 miles, rolling hills with a few climbs. On most rides I use one percent or less battery per mile, but I tuned both eco and mid level down and I turn the assist off for 20% or so of most rides. I...
