Are Yamaha ebikes available outside North America? I can’t find any for sale in Australia. I don’t know about Europe?? I suspect Yamaha Bicycles is a US company using Yamaha parts and name.

Fair enough, I suppose. As you say, the industry seems to use the terms assistance, support and amplification interchangeably. I was somewhat dejected a few months ago to read in this forum that the 35% boost of my Vado SL in Eco mode was actually more like 63% boost (35% x 1.8) on top of my...

Nearing home on yesterday’s ride, there is a short hill which maxes out at 5%. My wife tried L3 pedal assist just to see how it went, and soon found she was going faster than the 25 km/h limit for motor assist. However, she found that the motor assist cut out quite suddenly then cut back in as...

I don’t have a problem with “assistance factor”. That is different from amplification. Amplification = output/input = (rider power + assistance power) / rider power. As documented in Wikipedia (https://en.wikipedia.org/wiki/Electric_bicycle_laws#European_Union_definition) the EU rules for...

I don’t disagree with the figures, but with the (mis)use of words like amplification and factor. The way of measuring amplification is to divide the output by the input, and this is the “amplification factor”. If the SL motor contributes 1.8x rider input power, then the amplification factor...

The thumb/finger action is the Shimano standard. I assume it is protected by patents which is why SRAM is different. On my Vado SL, the Shimano lever will also work in push-push mode so it is, in effect, SRAM compatible. I tried the push-push operation but quickly decided I preferred the...

The Vado SL manual says the motor support will be reduced when the battery reaches 15-20% charge.

After a longer ride this morning (35 km with 287 m elevation gain) my wife is pleased with the revised boost setting on her Fx+. The Level 1 boost still provides a worthwhile boost on hills.

Quite a few e-bikes do have adjustable boost levels. Some can be adjusted by the user via a phone app while others require a trip to the bike shop.

We visited our local Trek dealer today, and they were able to tune the boost parameters on my wife’s Fx+ using a Hyena Windows app and special Bluetooth dongle. They reduced the Level 1 boost from 12% to 5% which should make the bike more controllable for low speed manoeuvring, and this was...

Has anyone had a chance to test ride an Fx+? My wife has reached the conclusion that the initial motor boost is too strong, even at the lowest setting, for safe low speed manoeuvring which seems to be a function of the motor control algorithm not responding in a proportional manner to the...

Check the measurements carefully to make sure you can obtain the correct seat height. The dropper post has limited height adjustment compared to a normal seatpost. For my wife, the target seat height was 710 mm measured from crank centre, and that worked out well with an M size frame on the...

It’s working very well. The dropper seatpost has been transferred onto a Trex Fx+ which has taken up residence recently and is the primary e-bike for my wife.

There are a number of e-bikes with integrated battery, which has both pros and cons for various people. It could also be argued that an integrated battery is better protected from moisture, as the electrical connections are inside the frame rather than external. Obviously, there are other...

I am puzzled. All info I can find on the Cannondale Treadwell indicates it has the Mahle ebikemotion X35 drive.

I have posted some info about the new Trek Fx+ and Dual Sport+ on the Trek forum. We bought one 2 weeks ago for my wife as a lighter alternative to her Trek Verve+2 so I am happy to answer any questions to the best of my ability. The rear hub drive and electronics is by Hyena, Taiwan. Trek...

Stefan. The reason for my question is that I have been surprised that no-one else on the forum appears to have taken delivery of one of the new Trek bikes. It is relatively common for multinational companies to test a new product in a small country/area prior to wider release. The Australian...

I wonder if Trek are selling them in Australia to test the market and the bikes, before releasing them in other countries?

Getting the back wheel out isn’t too bad. There is a compact round connector for the motor wiring. Contrary to the service manual, the part of the cable attached to the motor came secured by a cable tie which should be snipped in advance to facilitate on-road repairs. I just received a long...
