TTXGP e-bikers finish qualification run
Winner hits 102mph on Sulby Straight
Leccy Tech The first official practice and qualification runs for the upcoming zero-emissions motorbike GP – TTXGP - have taken place on the Isle of Man.
Rob Barber (above) finished the TTXGP qualification in first place
Of the 14 bikes that lined up for the first qualifying session, 10 managed to complete the demanding 37.7-mile Mountain Course.
The fastest bike over the line was ridden by Rob Barber, who managed one lap in a little over 26 minutes. Barber also hit a top speed of 102mph on the course’s Sulby Straight and averaged 84mph.
Barber’s Team Agni bike is based on a 2007 Suzuki GSXR 600, fitted with two Agni 95 motors and a 63-cell 16kWh lithium-polymer battery. His team said that the bike’s set-up produces 40 - 50 horsepower on average over the race’s entire length.
The second fastest lap was won by the Isle of Man’s own ManTTx team, thanks to rider Dan Kneen and his time of just over 32 minutes. Third fastest lap went to the US-based Barefoot Motors Racing team and rider Chris Petty.
TTXGP has been organised by eGrandPrix and kicks off tomorrow.
"The fanboys keep telling us how much faster EV's are than IC powered vehicles."
But they do point out that the torque curve for an electirc motor and lower inertia of a properly designed drive system means an EV (of the same mass as an IC vehicle) will *accelerate* faster than an IC powered vehicle. With a properly designed power management unit it will also do regen braking and recover braking energy. While not so important on a race with no top speed accleration and regen braking count for quite a bit in urban areas.
A good start. I hope this does become an annual event and improvement continues.
What about the crash in practice??
This was the funniest, slowest (and probably most historic) practice session I've ever seen. We were on the corner where the first TT electric bike crash occured, looked like a mechanical fault causing really low speed high side (rider looked ok, thankfully). The marshalls couldn't touch the bike (even after laughing their heads off) until thick rubber gloves were available and it took 4 of them to lift the bloody thing. With regards to the speed, yes top bike was >102MPH, 4th or 5th was sub 60MPH. I can't weight to see the highlights on ITV4.
On a serious note I can see the potential here for the future, but there needs much more development, particularly with safety (bikes fall over much easier than cars) and weight (not to mention NO engine braking).
Paris becuase when she goes down she does it fast and hard.....
The fanboys keep telling us how much faster EV's are than IC powered vehicles. And then when they are proved to be slower then we're told we've got to accept that they're new technology and will be faster one day. I accept that they are going to be slower, but not because they are new. Bear in mind that they've been around for a century and they were largely forgotten about because they weren't as good as their IC brethren. In other words it's not that they are new technology, it's that they have a hundred years or so of development to catch up on.
On the subject of performance 102mph should only require about 35bhp which is easilly possible with a 125cc petrol engine.
Much more worrying that the performance is that only 70% of the field managed to complete qualifying. It's hardly good PR for the EV as a whole that 30% of the bikes entered couldn't even manage to enter a time. Whether it's reliability or battery life neither makes good PR.
