Following the TT, I had a chance to take a Brammo Empulse electric bike for a quick spin. 54hp and 213kg might be a tad shy of the power to weight ratio of a GSX-R750, but the 90Nm of torque makes up for that off the line. It’ll do 128 miles around town on a full charge too, although that range drops to 58 miles if you sit on the motorway. And a full charge from completely empty takes 3.5 hours and costs, on average UK electricity rates, under two quid. But the fact that I’m even able to compare figures shows how far electric bikes have come in the last half-decade. What surprised me the most was how much the Brammo felt like a normal bike. It has a clutch, it has a gearbox, it has all the features you’d normally expect to find. The only odd bit for me was not warming up an engine before I rode off.

Definitely visit the site and read the article (so they get the clicks and maybe write more on electric bikes.

Not to be a nudge, but it seems silly to compare a bike that does 0-60 in under 3 seconds, to one that is over 5 seconds, and then claim that the torque makes up for it off the line.

The author trips over the continued misunderstanding of wheel torque vs motor torque.

The Empulse has been tested at a little under 5 seconds 0-60.
