It appears that the hubs are manufactured for a specific axle type, which suggests it may not be possible to change axle type.

I have been for a couple of short rides on my wife’s Trek Fx+ and I think I am starting to understand more how it works. It seems the torque sensor controls the motor assist by on/off switching rather than varying the assist in proportion to the rider’s effort. In effect, the bike behaves more...

Hi Stefan. Well, I bought one after researching the motor manufacturer (Hyena, Taiwan) and reading reviews of some other bikes equipped with Hyena drives. I don’t see the relevance of the figures you quote for Specialised bikes. In fact, we had a Specialised Vado SL 5.0 EQ on order for months...

The battery is 250 Wh, which is smaller than many comparable bikes (400 Wh for the Verve+). The relatively small capacity obviously minimises the weight, cost and bulk of the battery. My wife has ridden 35 km so far on her Fx+ and has used about 50% of the battery, although it is impossible to...

Well, we took the plunge and bought an Fx+2 this afternoon for my wife, as a lighter alternative to the Verve+2. Surprisingly, we havn’t found any reviews of the new lightweight Treks online. First impressions are good. We did a 5 km test ride, with me on my specialised Vado SL, and the boost...

This earlier post gives a good idea of expected speed vs. cadence.

I found a Trek/Hyena quick start guide for the new lightweight e-bikes. See https://trek.scene7.com/is/content/TrekBicycleProducts/HyenaGen2QuickStartGuide_EN-GB_2022-01-26.pdf Also, Service Manual at...

After delving a bit deeper on the Trek website, I discovered that the Dual Sport+ and similar FX+ have drive systems made by Hyena in Taiwan. I haven’t been able to find any reviews of the Hyena rear hub drive systems. There is some general info at...

I have been using the Hafny bar end mirror for a few years now, although sold under a different name in Australia (Azur Orbit). It is very good and far better than other bar end mirrors I have used previously. I recently fitted one to my wife’s Verve+2 and the insert just popped out of the...

Trek Australia are advertising the Dual Sport+ 2023 model ebike which is a new lightweight (17 kg) model with rigid forks and rear hub drive. It looks like it would suit many riders although the range would be limiting for some. I haven’t seen any reviews of this model. I wonder how the rear...

I recently fitted a dropper seat post to my wife’s Verve+ 2 as she was having trouble getting on and off with the seat set at correct height. I used a DNM CSP 31.6 mm seat post with 50 mm drop and external cable routing. Fitted to a Medium size bike, it suits the desired seat height of 710 mm...

Best to use a proper pedal spanner for removing tight pedals. There are numerous websites/videos on which direction they undo, including https://www.parktool.com/en-us/blog/repair-help/pedal-installation-and-removal But no need to do them up too tight, so don’t use the big pedal spanner for that.

There was no suggestion of charging in the hot conditions, just parking.

If humans can survive in the shade, I think the bike would be Ok.

I remember when it was only software that came in Ver 3.1, etc.

Very strange! However, I am going to keep my 35/100, 60/100, 100/100 settings as they suit my current needs, and maximising range is not my priority.

Stefan. I don’t understand your figures. Where do you get the 1.8 factor? For SL bikes, everything I have read from Specialised says that the motor assist (mechanical) power is a maximum of 100% of the rider’s power in Turbo mode. To explain my original post, with 35/35 setting for Eco, when...

Stefan, I disagree. It only has an effect when the rider power is over 240 W which, for most people, would only occur for short periods such as overcoming a short but steep hill. Therefore, the effect on range is minImal. If you can sustain over 240 W for considerable periods, you probably...

This has probably been discussed before, but one of the first changes I did to my Vado SL 4.0 EQ setup was to up the motor power limit in Eco and Sport modes to 100%. With the default settings of 35/35 and 60/60 the motor power is limited whenever the rider power exceeds 240 W, to 84 W in Eco...

If you know someone with a 3D printer and design skills, it would be relatively easy to make a custom mount. I have made a rear-facing mount for a Topeak rack which we used to film scenic rides in Switzerland in 2018.
