A2B Alva+ e-bike

The A2B Alva+ is one of the San Francisco-based e-bike builder's most fully featured electric bikes.

The 13.2Ah battery provides the Alva+ with enough juice to roll about 40 miles under assisted power. Your mileage will vary depending on how much you weigh and your set level of assistance.

The battery pack can be locked to the frame with an included key, but you'll need to bring your own lock to secure the rest of the bike.

The battery connects to the bike's electrical systems via this simple, magnetic plug. The charger uses an identical plug.

The Alva+ is hefty, 66 pounds to be exact, but most of the weight is concentrated in the rear, where the motor and battery are located.

You charge the battery with the included AC charger. An 80 percent charge from nil will take about 2 hours. A full charge takes 3 to 4 hours.

The rider's pedaling effort is sent through a Shimano XT seven-speed gearset.

Pedaling gear is chosen by wringing this twist-shifter. Your position is indicated by ringing the bell next to it.

Twisting this throttle allows the Alva+ to motivate itself completely under electric power.

However, to get the most range and power out of the Alva+, you'll want to add your own pedal power to the system.

Sensors in the bottom bracket detect your pedaling effort and add electric assistance to the mix.

The Alva+ has a stated top assisted speed of 24 mph. However, heavier riders may get less speed and strong riders can continue to pedal beyond this limit under their own power.

Hauling the ebike to a stop are disc brakes affixed to the front and rear wheels.

The hydraulic disc brakes are easy to modulate and have good feel, but I think I'd rather have easier-to-maintain mechanical stoppers.

The front wheel is a quick release and is easy to yank off if you need to transport the Alva+ via truck or SUV. Lifting the hefty e-bike into a vehicle, on the other hand, is another matter.

The Alva+ features integrated fenders at both ends, which means you can ride it in the rain without getting your backside soaked.

At both ends, you'll find integrated LED head and taillights for increased safety when riding from dusk to dawn.

The front fork has well over 2 inches of travel, which makes short work of curb-hopping and steamrolling potholes.

You can interact with the Alva+ and its various drive modes via this cycling computer.

In addition to battery level, the computer can display an odometer, a trip odometer, and the current speed. Here is also where the rider will adjust the level of assist by twisting the silver knob on the left side of the display.

The Alva's ride is smooth thanks to a wide saddle and its upright riding position, which also promotes good visibility.

The Alva+ rolls on the widest bicycle tires that I've ever tested.

At 2.35 inches wide, these tires contribute to the e-bike's smooth ride, but also add a bit of off-road ridability. The 24-inch wheels that they're wrapped around are smaller than your average road wheel, but satisfyingly maneuverable.

Most of the cabling that you'll find on the Alva+ is routed internally, through the aluminum Y-frame, so there's not much to catch on.

It's heavy and unwieldy when you're dismounted, but the Alva+ carries its own weight and ends up being a nimble ride that flies up hills with the greatest of ease.
