Another price increase in Poland (as of today). Vado SL 4 non-equipped is 18,000 PLN now.
2023 Trek Fx+ and Dual Sport+
- Thread starter Richard Stallard
- Start date
Check Trek's website. Not available on line but it seems a couple shops somewhat near me have decent availability of colors and sizes. I'd be interested in either a Medium or Large and both shops have several choices. If the numbering is following the regular FX line, FX2 is relatively low end. Will be interesting if they come out with carbon fiber and higher componentry versions of these later.
Almost sounds like the motor assiste is similar to riding my Specialized 4.0 SL in Turbo mode. Starts/accelerations give a less than smooth sensation compared to the lower assist levels.
The new Treks are available in the U.S. now. My local Trek dealer should have received a small Dual Sport+ last week. I will likely go in to check it out this week if they haven’t already sold it. The price is very appealing, and the Hyena drive system has gotten decent reviews when used on other bike brands (e.g. the Cannondale Treadwell).

I am puzzled. All info I can find on the Cannondale Treadwell indicates it has the Mahle ebikemotion X35 drive.
The only thing that I see as a knock on these models is the fully integrated battery. For commuting most people need to be able to remove the battery to keep it out of the elements for long periods of time because a lot of people don't work in an office building.

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 bikes to choose from if you decide a removable battery is best for you, but others may make an equally valid choice to favour the integrated battery. It’s great that so many options are available.
I get it. If I didn't use the bike for commuting to work I would probably get one of these. Having the battery exposed to the heat and cold for 8 or more hours a day is my concern for the battery.
I like the bikes and the price is right too.

unless you park your bike in seriously unfavorable conditions, i wouldn’t be too worried about this. are you thinking sub-zero or 100+ temps?

hmmmm. that’s disappointing - why use a torque sensor if it’s an “on/off” kind of situation? i was thinking about one of these as a commuter replacement. are the assist levels programmable?
Not sure of the availability now - but Trek says a range extender with 250 Wh is an option. Presumably it is somewhat easily removable and could be charged indoors while at work. Also presumably if the range extender is fully charged while the internal is lower the bike will draw from range extender until the two batteries are equal in charge. Or there may be a setting that would allow using the range extender first. If this is the case and 250 Wh is good enough for you commute - the bike with range extender should work for your commute. Doesn't address your concern of leaving the internal battery along with the bike exposed to the elements.
My bike is locked up outside for roughly 10 hours a day and I know if it had an internal battery it would be damaged in the summer on those 100 degree days.

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 torque sensor. According to the Hyena website https://www.hyena-ebike.com/sensor/ the torque sensor delivers an analogue voltage proportion to torque, so a proportional (rather then on/off) response should be expected. I emailed Trek Australia customer support about 2 weeks ago to ask if the behaviour of the bike indicates a fault or if it is performing as intended. No response yet apart from an acknowledgment.

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 verified by a test ride in the carpark. The numbers don’t quite make sense as 12% seems low to start with, assuming it refers to 12% of the maximum 250 W motor boost. The effect of the change on regular riding won’t be known until we do a longer ride, weather permitting. The change can easily be reversed or further amended if need be.

Wow, that looks like a wonderful change.
My 2021 Aventon Pace 500 had an aggressive surge for its intended use. City riding, with stop & go, and tight maneuvering around various obstacles. Loved the comfortable step through frame but just didn’t feel safe on it. Sold it a couple months ago. Maybe more future ebikes will come with a programmable acceleration.
Please post how your wife likes the change.

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.

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.
