One bike you might check out is the Gazelle Arroyo. The 2017 version got one of Court's 2 "best picks" for a city electric bike (https://electricbikereview.com/best-electric-bikes/), and they have only improved since them. There are very few best picks. I own the 2018 model. The 2019 Elite...

I had thought that most legislation allowed throttles up to 20mph for class 3 bikes, a sort of class 2+3. But, looking into it some more it appears that I am wrong. Legal definitions of class 3 don't seem to include throttle to any speed. For example, California defines it in section 312.5 as...

The US Class III standard is for pedal assist up to 28mph and throttle (if one is available) up to 20mph. That is probably why it behaves this way. If the throttle assisted the speed beyond 20mph it wouldn't be a class III bike.

The article at https://www.bicycling.com/news/a24110027/bike-helmet-safety/ gives a good overview of the pros and cons of helmet use and requiring helmets. It references a 2017 study review (https://academic.oup.com/ije/article/46/1/278/2617198) that found that helmet use significantly reduced...

Mickey - one thing you mentioned in the video is a refined eMTB mode, what adjusts the amount of assistance based on pedal power. But isn't that what a torque sensor does? Torque sensing bikes are supposed to output power proportional to the power you put in, and Bosch seems to do a decent job...

It sounds like you liked the feel of the Bosch motor. One bike you might try is the Trek Verve+. (https://www.trekbikes.com/us/en_US/bikes/hybrid-bikes/electric-hybrid-bikes/verve/verve/p/17470/?colorCode=blue) It is available in both a low and high step, uses the Bosch active line motor...

Why do you call it a 350 watt motor with a 500 watt peak? If at level 5 RAD puts 750 watts into the motor then wouldn't you say the motor is 500 watts peak? Also, they recommend not exceeding 500 watts for longer intervals. Thus, it seems the continuous rating would be 500 watts.

As others have mentioned, both have advantages, with hub motors generally being cheaper, while mid-drives generally giving higher torque and efficiency when climbing hills when you use low gears. However, perhaps one of the key differences is not in the drive itself but in the sensor type...

You may run into problems. The standard limit for lithium batteries in carry-on luggage seems to be 100 Watt-hours. Airlines may allow more with special permission, but most seem to set the limit at 160WHr. See - https://www.faa.gov/hazmat/packsafe/more_info/?hazmat=7 -...

The higher end Trek bikes you are describing probably use the Bosch Performance Line motor. This motor spins the chainring 2.5 revolutions for every revolution of the pedals. Also, the pedal input to a separate gear from the motor/chainring output likely makes it easier to sense the torque of...

One nice thing about the Bosch Active Line motor used in the Trek Verve+ is that it is very quiet. I test rode a Trek Verve+ and I couldn't even hear the motor in the lower power levels (Eco and Tour). This contrasts with the Bosch Performance Line and many other motors which can be annoying...

You might check out the iZip E3 Path Plus. The normal price is ~$2600, but there are a few sizes/styles available for $1500. (Even if the show sold out on their web site, sometimes a local bike shop can get one.) I really liked the responsiveness of the bike and almost bought one, but bought...

I don't think the Bosch system cuts off at 18 or 18.5mph (displayed), but rather gives 100% support to a certain speed, then gradually reduces support until it hits zero at 20mph. The support at ~18mph becomes low enough that you tend to get to this speed on level ground with medium effort...

I also own a Gazelle, the Gazelle Arroyo C8 HMB. You can see it at https://www.gazellebikes.com/en-us/gazelle-arroyo-c8-hmb-v5. (I don't think the Ultimate is available in the US.) The Arroyo is a low-step and the I have only seen any frame flex/wobble once when riding without hands...

The other possibility is simply that the OP reached the maximum torque/power level for the motor. If the graph near the bottom of (Link Removed - No Longer Exists) is accurate, the Yahama motor has the same maximum output torque in ECO, STD, and HIGH modes. It just takes less input torque to...

The OP indicated that he had downshifted to the 2nd lowest gear on the rear chainring, and the smallest (lowest) gear on the front chainring. So I don't think downshifting too little is the issue. On the contrary, it may be downshifting too much. Yamaha drives really don't like high cadence...

The link to the US version of the range calculator is at https://www.bosch-ebike.com/us/service/range-assistant/.

While none will match torque sensing, not all PAS/cadence sensing systems are created equal. A couple that I tried are notable. Rad Power has a PAS system where the input power, and thus the torque (at lower speeds), is proportional to the PAS level. Thus, if you dial in a low PAS level you...

Given that the 500w and 750w motors are exactly the same, you won't be more likely to damage the 500w motor by pulling the trailer. If anything, as others and Rad Power Bikes mentioned, limiting the motor to 500w means less chance of damage to the motor. It is the heat buildup from running at...
