...We know Rob could cycle the whole thing, and have a full battery at the end so I fail to see any “interest” in the ride...

But there is... 🙂

Can I just get something clarified?
Am I going to be forced to ride an e-bike if I want to smile whilst I am riding?

I don't think so, I said "This is ****ing mint!" out loud whilst riding my bike down an old favourite descent the other day after a long spell off the bike. It has tiny 650b wheels, minuscule 2.3" tyres, I was on my own, and my frame isn't even BOOST.

Cant fathom why my catchy tagline suggestion of 'Rob discharges on the downs' didnt make the cut. Oh well, may the electrons be good to you and hold out till Eastbourne Rob 🙂

I’ve done 34 miles on half a bosch 400 battery.
I weigh 20 stone, and i did walk up one really steep hill.
But on the later flatter bits, the most economical way was to actually sit on the speed limiter.
Acceleration uses a lot of power, pulling a fat knacker up steep hills does too.
I’m interested to see how op gets on tbh. Hope he manages it.

Rob went through QECP at 08:19. Already punctured before Milburries, Stans did its job with a tubeless repair slug.

Battery still on 5 bars.

500whr battery over 100 miles sounds impossible but in reality it is do-able.
If you were to use zero assistance for all decents , and all the flat sections and keep the battery for the stiffer climbs then you need the battery for approx 5hrs of the whole ride
If you could add 100W to your output for those climbs then its job -jobbed.
A std distance rider should be able to tap along at 150W all day on a pedal bike , with an up rider+ bike weight of roughly 85kg.

By adding a battery and motor and an extra 10kg of mass the Watts per Kg of overall weight is significantly increased if run at 100watts of assisatnce 85/150 V 95/250

So 10 climbs of 30 mins @ 100w gets you there . I actually dont think there are 10 climbs that will take 30mins. As with elec assistance and a theoretical speed of 10mph uphill , 10 x 30mins = 300mins = 5hrs = 50miles @ 10mph. So using that logic there would be no flat sections half up and thn half down.

There has to be an allowance for going slower on the flat and on on any gentle rises where using elec would be wastefull.
Thinking about the route, in reality there are probably 20-25 bits where ~ 10 mins of boost would get you over the top alot quicker and alow the battery to recover a tiny bit

can't you just stop at a servo to stuff a load of ginsters and fizzy snakes in the battery when it runs out of energy?

Rob got to Amberley 1/2 way at 11:05, still 5 bars of battery left. Think the plan is to start using the boost a bit more now. Up Amberley Mount for sure.

I would wait until past Truleigh YHA to start hammering battery, big hills after that and they come up fast

Edit: I just need to refresh my screen ha ha

He's about to go within half a mile of the office, 4 hours to Eastbourne from here isn't too difficult.

Itford is the worst of them, hate that one once you are on the grass.

Proper good effort. 👍👍🥳

I thought he’d be done in by Cocking. 🤷‍♂️

He's coming in from the wrong angle in that photo, presumably he's been to the old tap not the new one, that must of cost him at least 25 meters, good job it's flat

How much power left at the finish then? Or did he beast it up the final hill to use it all up?

Robs finished at 16:14.

4 bars at Alfriston, he was so quick up there that he beat me through Jevington. Max attack up from Jevington saw in in Eastbourne with one bar left.

I'll create an album rather than post lots of pics.

10h14m… so… the obvious question is: what's the quickest Rob's done the Way on a non-motorised bike? 😉

Excellent, well done. Can't wait to hear from Rob himself.

Having done it today and getting to Alfriston pasty stop with 3/4 of the available juice left then surely next time you could knock maybe an hour off that with more 'linear' use of the available electrons.

I don’t think the answer to that question is going to increase the sales of ebikes 😉

Maybe an attempt at the double on a YT Decoy with its bigger battery?

Brilliant! Just brilliant!

I just love this kind of challenge. Forget round the world at a record speed. This is much more my kind of slightly daft but fun challenge.

Looking forward to the write up and more pics.

Cheers

Sanny

Well done.

So much distance was power actually used for? 4 bars left right up till the last 20 miles, and then used up 3 bars to end? (dunno the route or area at all, so I'm guessing after a quick look at the map and comments?)

So hang on.. It took ten and a quarter hours..
Yeah, I'd want to know robs general SDW time, cos it almost seems as if he had to go slower, just to eek out the battery?

I dunno.. I'm a bit fick!

Topic starter
 

Hi all, been for brekkie and a quick gym so sorry for the slow update.
I will do the details later, but safe to say the 'Beam me up, Scott E' was fun to ride - you can just point it and shoot. I really enjoy the suspension set up but 130mm is more than the SDW really demands, it did make for a faster ride on the bumpy bits and more fun approaching gates than my Tallboy permits.
I don't actually know my best time for a SDW - I allowed 12 hours a leg when initially plotting the SDW Double Double and then tweeked the schedule and I did have a 14 hour time for this e-thing in mind before I got on the Scott back in November but I reduced that to 12 hours in the weeks before announcing the challenge (I kept it a bit QT so nobody else would beat me to giving it a bash!)
Super pleased with a 10.25 hour crossing and lots of that goes to the support crew who were really slick.

Got to wash the bike as it squirted loads of Stans Race all over whilst puncturing before Holden Farm - my first puncture for simply ages which took 10 mins to plug, coz I'm raw at doing it.

More later.
