& No dinosaurs! :D Numerous well-known ebikes in this tough test-course: Bionx, Biketec Flyer, Dolphin (aka Swizbee), Ezee, Sparta, Cyclone & Velectris, some with different power motors or models represented e.g. 250W & 500W Bionx, and some on recumbents too, plus at least one tandem!

I found the link from the cyclepoint site, but for those who haven't seen it:

Jurassic Test

Just choose links for more information (the last one is just an application form I think!). Its all in french and I couldn't get babelfish to translate the pages, but you can still translate blocks of text.

Bulletin of inscription

The test is over a 50km (30mile) course with ~900m ascent aswell as descent and points awarded for both speed and energy economy, maximum 1000 points for times under 2 hours, points then subtracted according to energy used. Ok, so rider strength plays a big part in the final results, but it looks an interesting test all the same. :)

Full aims below, or just watch the video - see how many bikes/kits you can recognise in the video! :)

The full 'provisional aims' (much of it simply babelfish translated...):

Idea: Jurassic Test 2008 is an exit of vehicles without fuel on a demanding course in the Jura Suisse, at the time of the day of the sun. Power, autonomy, effectiveness… here's the aims:

Vehicles: electric bicycles, electric scooters, electric carriers, electro-solar machines. The vehicles circulate under their own authorization (it is of an exit of test on open roads and not about a race).

The course: 50km approximately, 900m of ascent, with one of the most demanding cols of the Jura (col of the Pivot), on minor roads of the Jura. In theory Holy-Cross/Bullet/Mauborget/Villars-Burquin/Vuiteboeuf/Baulmes/Collar of the Pivot/Gittaz/Holy-Cross, plus a final 5km on a circuit in the village of Holy-Cross.

Aims: the goal is to approach the level of 1000 points, that is the only objective.

Completing the course merits 1000 points if it is made in less than 2:00hrs, 900 points in 2:15, 800 points in 2:30 (- 100 points by 1/4h additional until 4:00 = 200 points).

In the event of arrival after 4:00hrs, not classified. (Advantage fast vehicles and good autonomy)

Energy: (in theory in form electric, in any case without fuel) stored and transported upon the departure “is bought” by sections of 100Wh:

10 points per 100 Wh for 100-500Wh
3 points per 100 Wh for 600Wh-2kWh
1 point per 100Wh for 2.1 kWh

If the vehicle transports several people of adult size during all the course, one divides this cost by the “momentary quotient” (1.5 per “passive” adult, 1 per “active” adult (pedals)). (Advantage the economic vehicles, takes account of the capacity (thus size) of the vehicle)

Energy charged during the race by replacing the empty batteries by full batteries costs the double of the preceding price.

Energy charged during the race while connecting at a not tractor drawn electrical installation does not cost anything (but it wastes time and there are few possibilities during the long rise with share a generator).

In the same way the energy generated between 9:00 and 13:00 by a carried installation (eg: carried solar panels) does not cost anything.

The surplus of remaining energy on arrival does not give the right to any no-claims bonus.

Exceptions: Cyclists (without electric motorization) are authorized to join this test course, they will be used as comparative data. But they will not be the subject of a classification in Jurassic Test.

Schedule:
9:00 - 10h: Explanation of the instructions, the course, gathering on the starting surface
10:00: Departure
12.-13h: The competitors finish their 3:00 while turning on the circuit
13.-14h: Exposure - (tests) of the vehicles for the public, the press, handing-over of the prizes

Although 11 bikes & riders made it under 2hours, (times & final rankings) the two Bionx bikes which which came out on top overall (only 4 and 13mins behind the fastest bike time) used the smallest capacity battery but can use regenerative braking to recharge en route.

I've read on the forums from Bionx owners how this seems to be quite effective in practice and was wondering how much it might have helped by recharging in this test, given the very long downhill section (~900m descent in total), but it does appear at least to have allowed them to use a smaller battery? How much does the amount of energy recouped compensate for the higher energy output of a stronger cyclist for example? I guess theres a time penalty for using it too, but its never been clear to me how much it slows descents.
