The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
Of course the specs are nuts. Shimano Deore XT Shadow+ drivetrain, Magura MT4 hydraulic disc brakes, Mach 1 rims, and Schwalbe G-One tires make this not only an incredible commuter, but really a solid racing bike if you want to challenge another ebiker. The G-One tires I just love. They’re slick enough to keep you up to speed, but have a good amount of knobiness so that you can handle bad weather.
Is it worth $1700? I’ll let you be the judge. I don’t have a lot of experience with commuter ebikes so I don’t know how it compares. I do know that most of the ebike conversions I’ve seen look like science experiments. The Buffalo could pass for a normal bike, and look a little more accessible to a first time ebike user. So, although I’m not planning on riding this, I am planning on using it. So I’ll keep it around for a while and let you guys know what I think long term.
Unlike most e-bikes, the Brompton's battery is integrated into a bag that sits on the front of the bike. While that detracts slightly from the classic, streamlined design, it's handy as it can be unclipped for charging or riding as a regular bike – it's probably one of the easiest to ride without battery assistance thanks to its weight. The battery also powers two lights for safe commuting.
Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
