I have been asked by David Henshaw to draft some rules for this event/trial so some meaningful and useful results can be gained, David has also suggested that a speed distance formula be employed to level the playing field. Below is an extract from David's email explaining the formula and also the draft rules

It occurred to me that a fair way of taking account of speed AND range would be to come up with a formula that featured both.Looking at our recent tests of Ezee and Kalkhoff bikes, we have these results by simply adding together milage and speed:
Nano Brompton 47.9 miles @ 13.4mph = 61.3 points
Kalkhoff Pro Connect 31.5 miles @ 14.7mph = 46.2 points
Ezee Sprint 29.3 miles @ 16mph = 45.3 points
Ezee Torq 22.8 miles @ 18.9mph = 41.7 points
Kalkhoff Aggatu 26.,7 miles @ 14mph = 40.7 points
Gazelle Easy Glider 19.5 miles @ 13.2mph = 32.7 points

This is quite an interesting result, because it's a great leveller, but biased towards the bikes that do the greatest mileage. So for three batteries, it would be total milage plus speed in mph x 3.
In practise, of course, the nano rider would be pretty impressive to do nearly 150 miles in a day, so it simply couldn't win so starkly. A Sprint ridden with great care would have just as good a chance


Draft Rules

1.The event is not a race, the trial is to establish a machine's efficiency not its outright speed.

2.Bikes must be UK street legal.

3.Batteries must be standard retail items as supplied normally with the bike.

4.A maximum of three batteries may be used and must be carried on the bike at all times.

5.Participants may carry a basic repair kit, items allowed 1 tyre, 1 inner tube, 1 drive chain, spare chain links, spokes, puncture repair kit, tools, spare fuses/relays, gear and brake cables.

6.Participants must carry a first aid kit and a mobile phone.

7.All bikes, batteries, repair/ spares kits and 1st aid kits must be submitted to the scutineer 1 hour prior to the trial starting. Any bikes/ batteries found not to be street legal or showing any signs of modification from a standard retail product will result in disqualification . The scrutineers decision is final.

8.Bikes must remain in scrutineering until the start of the trial.

9.Nobody may enter scrutineering unless invited by event officials

10.Two minutes prior to the start riders only may enter scutineering to collect their machine and proceed directly to the start line.

11. A detailed route book will be released to the rider at the start line, details of the route will not be released prior to this time.

13. Riders will be started individually at 1 minute intervals.

14.All Participants must visit all check points on the course failure to do so will result in disqualification.

15.Support vehicles and staff must remain at the start finish area and will only be allowed to leave to collect bikes and riders that have retired from the trial.

16.In the event of a participant retiring from the race, the rider has sole responsibility for their own and their machines recovery. The event organisers will not be offering any recovery service.

17.The rider will be responsible for their own safety, the trial is held on public roads and any infringement of the highway code or dangerous riding will result in disqualification.

18.When the rider arrives at the finish they must proceed directly to scrutineering, failure to do so will result in disqualification.

19.Results will be released when all machines that have finished have been released from scrutineering.

20.If a rider / machine is disqualified for whatever reason. no appeal will be accepted, the scrutineer's/judge's decision is final.

21. All participants must register 7 days before the trial. late entries will not be considered.

by "street legal"...

does this mean that NO deristricted bike can enter ?...

does it mean that no bike that had smaller sprockets added to go beyond the legal 15 mph can enter ?..

I am not sure if any Cytronex riders are considering entering this event but the rules would seem to exclude them (unless they did the majority by leg power alone). It is difficult to see them doing many more than 60 miles on three very small batteries.

Hi Riggo

Can you confirm the route is a loop and not an A to B if you'll pardon the pun

Which has been one of my points on this bike Hal. I think it's a great concept for those who prefer a proper bike, but it isn't up to the current state of the art on range, 20 miles being yesterday's stuff. As has been pointed out, with the strong rider necessary for this event, the standard Pro Connect can do the T.o.B 113 miles with about two and a half batteries, three easily, and at the same average speeds Cytronex users have been reporting (12.5 to 13.5 mph).

The two war cries from e-bike users over the years have been "more power" and "more range", and "cycling qualities" haven't figured anything like as strongly, that call mainly coming from confirmed cyclists rather than from typical e-bikers.

As Cytronex say you can always have two batteries for longer range and I am not sure what the point is of limiting the number of batteries - it might be more interesting having a battery weight limit (and I am sure the Cytronex would struggle with that). Just seems a bit arbitrary to me that's all (as this this is a deliberate design feature of the bike).

I think the battery limit is just that Wai Won wanted to make a point about the eZee and Panasonic relative abilities, as he seemingly doesn't believe the Pro Connect can do 30 miles on a battery. I know it can, the heavier Agattu had no trouble doing more than that in very hilly territory with this 71 year old on board in chilly November/December weather, not the best conditions for battery performance.

I believe the event is now going to take place on the 10th September, the day after the T.o.B, more sensible I think.

Sorry but, I think This event seems about as pointless as you get.

Yes as standard my Agattu would do 37 miles on a battery - my Torq wouldn't get near that but it would go a bit faster. I am not sure what it is supposed to prove either and if it is a bit of fun why all the rules about number of batteries? Are there any Pro-connects entered anyway?
