Most performance bikes have a range around 120-150 miles. Triumph Daytona 675 for example is 125 miles. Enough for a long weekend ride, or a regular commute without too many refills a week.
Sure, but I could top-up that Triumph and extend my range pretty much anywhere as gas/petrol stations are everywhere.
With an electric bike, the options start to become limited and a greater range is desired.
I couldn't see a re-charge time on the Mission site, but the Saietta cites a 3.5-8 hour full re-charge time dependant on the power supply available.
Depending on temperature/weather a ride from London to Birmingham would be risky. Unless you'd planned in advance and left at first light so you could ride back at dusk, you'd probably have to stay overnight even though the ride would have only taken a couple of hours (max). That may be great if you want a day out somewhere, but less great if you want a day out riding.
And this is being marketed as a "superbike". But it couldn't participate in existing race events (even if rules permitted an electric bike), as the distance of a race at Silverstone is 263 miles. Both the Mission and Saietta could not complete even half the distance of a race event, and even if you step down to track day events the electric bikes wouldn't last the event (7 x 20 minute sessions @ 80% speed is beyond the range of the bikes... you'd hope to go faster than 80% speed anyway).
So what is the real current usage of a bike with such range and re-charge time? Commuting.
Suddenly that's one hell of an expensive commuting bike.
You're not wrong. From riding myself I remember many times when a ride went a bit further, or a bit wider than expected and one of the group would need to top up, so there would need to be a lot to make this viable and relaxing.
For commutes, it's fine. It's almost like it should be a sporty tourer, but then that's no fun on a press release.
I think given the Formula E plan of having 2x cars per race, racing is actually more applicable. Racing will challenge how these bikes are recharged/replaced quickly.
The most often overlooked issue with press-release-bikes, is that many motorcycle owners will show terror at the thought of having a no-brand bike. The cost of parts, servicing, or replacement if it gets crashed (it will) is so high, that it really is only a toy for the naive or rich (or both).
If you want more... you get a tourer.
