E-bike batteries are, for the most part, a collection of 18650 batteries, packaged together and welded in series and parallel, attached to a battery management system (BMS). A "dead" e-bike battery may only have two or three truly dead cells inside, while the remainder work fine. This is useful knowledge that, for the most part, very few e-bike owners can really use. Arc welders are not a common tool to own, and most e-bike batteries are not designed to be opened, safely or otherwise.

French firm Gouach, essentially a three-person company, is pitching its Infinite Battery as the opposite of this status quo. It's a durable, fireproof casing into which you can place and replace 18650 batteries using only a screwdriver. It keeps you updated on the status of cell performance and heat through a Bluetooth-connected app. And it's designed for compatibility with "90% of existing e-bike brands," or you can upgrade an existing "acoustic" model.

I initially felt bad for the Medeo T9 City e-bike that Gazelle sent me for review. Not through any fault of its own but because I had just recently ridden Gazelle's Eclipse C380+, an all-inclusive beast that retailed for roughly 2.5 times the price of the Medeo T9 City. Would the lower-priced bike, with different versions of some of the same hardware, suffer compared to its beefier brethren?

Short answer: not really. The Medeo T9 City isn't trying to dominate the road; it just wants to get you where you're going. It has the same kind of automatic electric assist level shifting, just packed into a smaller handlebar display instead of a center console. It has chain and gear cogs instead of the Eclipse's belt drive and stepless shifting, an external battery instead of an inline, and a 250-watt Bosch Active Line motor instead of a 350-watt Performance Line Speed.

I think the Medeo T9 City likely makes for a good first or second e-bike, or perhaps a nice upgrade if you're prioritizing comfort and transport. Given its hill-smoothing motor, wide range of sizes, stable ride feel, and the backing of known bike brands, you could do much worse than a Gazelle with a Bosch motor.

Angell, a French smart electric bike startup, has announced in an email to customers that the company is declaring insolvency and approaching a court to ask for judicial liquidation. “It’s over for Angell,” said company co-founder and CEO Marc Simoncini on Instagram.

Post-pandemic, my creed became "Bicycles deliver the freedom that auto ads promise." That belief is why I’ve almost exclusively used a bike to move myself around Portland, Oregon since (yes, I have become a Portlandia stereotype).

However, that lifestyle is a lot more challenging without some pedal assistance. For a few summers, I showed up sweaty to appointments after pedaling on a $200 single-speed. So in 2024, I purchased the FX+ 2, based primarily on my managing editor’s review. It’s since been a workhorse for my daily transportation needs for the past year; I've put more than 1,000 miles on it in eight months.

So given my experience with that bike, I was the natural choice to review Trek’s upgraded version, the FX+ 7S.
