Topeak Modula Cage II Adjustable Bottle Cage

The Modula Cage II adjusts with a thumbwheel to grip bottles from small cycling bottles up to disposable water bottles and some insulated tumblers, which makes it the right cage for e-bike riders who do not own a dedicated bike bottle. It bolts to standard bosses. Many e-bikes lack bottle bosses because the battery takes the downtube, so check your frame; if there are no bosses, you will also need a strap-on adapter or a handlebar cup holder. It is plastic and aluminum, light and cheap. It will not hold a bottle as tightly on rough trails as a dedicated cage.

CamelBak Podium Chill Insulated Bottle (21 oz)

In a Frisco July the difference between a plain bottle and an insulated one is whether the water is drinkable after twenty minutes. The Podium Chill is a double-wall squeeze bottle with a self-sealing jet valve that does not leak in a bag and opens when you squeeze. It fits standard cages, though the insulated version is a bit stiffer to squeeze than the plain Podium. It is dishwasher safe. It is one of the more common bottles you will see on e-bikes precisely because it is simple, cheap and keeps drinks cool for about as long as a neighborhood ride lasts.

Best for: Hot-weather riders · Commuters and neighborhood loops · Bags and backpacks (no leaks)
