Kudos Rapide gets 108 miles out of a 10.4 Ah battery.

[awol]

This has been a thought provoking moment I am going to turn MAX Amps on my controller down to 10.5 A. That means I will be running the battery at 1C tops and at 36V nominal still be getting up to 378 Watts in assistance level 5.

KD a good test would be to have the same bike ridden over the same course with different riders with the same instructions. Then you could do some marketing like:

Sports rider up to xxx miles
Reasonably fit 45 year old up to xx miles
Unfit wheezy asthmatic up to x miles

That in my mind would be really useful for the punter and you would be very seriously thumbing your nose at Bosch et al.

I might try laying off the pretzels and nibbles for a while and see if my wH per mile drops to the average but I can't see it happening. (me lying off the nibbles I mean)

It's going to be interesting to see how the Woosh Karoo that I currently have for review will fair in all of this talk of mileage.

First ride today https://www.strava.com/activities/508370131

17.9 miles, 1,485' of elevation gain, including this section http://veloviewer.com/segment/610650/Kidd's+Hill

• Distance 1.5km
• Elev Gain 136m
• Avg Grade 9.1%
• Max Grade 15.4%
• Climb Cat 4

The highest power level (6) was used for the whole ride length, legal cut off point not altered, and the bike returned without having dropped one bar of battery level. Kidds hill was a real bastid of a climb on it though!

Road works and traffic calming also slowed things down.

Ride completed by EddieJ aged 49yrs 10 months, weighing in at a healthy 75kg, and currently nursing b*****k infection! Not pleasant when trying to cycle!! Very grateful for the comfy saddle that the bike has though.

must get kd cyclist to try my vita uno/kudos I seem to be 100miles shorter in range from my 10.4?

or is the new rapide battery powered by startrek di -lithium crystals

must get kd cyclist to try my vita uno/kudos I seem to be 100miles shorter in range from my 10.4?

That means you're getting the usual sort of range that I quoted earlier.

At the average of 12 Wh per mile, your battery gives 31 miles range, corresponding to KD's 130 less 100 short as you posted.

you have to eat your 3 weetabix before you set off.

I eat Weetabix chocolat minis with muesli mixed in. Is this why I'm getting such great fuel economy?

As Frank Curran of Powabyke often remarked when he was posting in this forum, the active members in here are not average e-bikers, they're enthusiasts. The peculiar low or high consumptions that are quoted, from 5 to 25 Wh/mile are representative of that, and at any one time there's perhaps less than 100 of those members active.

The 10,000 members who only enter to post very few times and then disappear are average e-bikers. From their posts we know that they return the averages Kenny and I have indicated, and they certainly don't get the long ranges a few enthusiasts get. Their common complaints about the manufacturers' range claims emphasise that fact. I'm quite sure that's also true of the circa 150,000 e-bikers out there in the UK who probably never enter an e-bike forum.

an MTB converted with BBS02 riding at 28mph:
5wh/m + 1wh/m (knobblies) + 1wh/m (full throttle) + 1.5wh/m (coil spring forks) + 15wh/m (speeding)=23.5wh/m. A 15AH battery would give about 22 miles range.

Wow.. That is almost exactly correct for me on average during the winter.
Luckily I have 48Ah of batteries.
During the summer I get around 15Wh/mi as I tend to ride slower,pedal more and weigh less.
We also have a lot less wind in the summer.

 

[anotherkiwi]

I had my Eureka moment (this has been trotting in my mind since last week).

Going up hills I use 10-14 Wh/km and going down 0 Wh/km! As in my neck of the woods you are either going up or coming back down the average is around 5-7 Wh/km. So yes! I do need electrical assistance but only on half of my journey (maybe less because S. Sebastian is flat).

I'm glad I figured that out I feel much less guilty now

 

[flecc]

Going up hills I use 10-14 Wh/km

So 16 to 22 Wh/mile uphill, and 8 to 11 when averaged with the downhill zero use which I'd happily agree is in normal ranges. A little on the fitter rider side of the 12 Wh/mile that Kenny and I are quoting.

As the thread has been bumped up again, so far I have only had time for three rides on the Woosh Karoo, but using the highest power setting for each ride, I'm now up to 53.20 miles with 4,245' of elevation gain and three bars of battery level still remaining from the 13ah power pack. I'm quite impressed with that, especially given this climb.http://veloviewer.com/segment/610650

[EddiePJ]

After another short ride today, the total mileage is now up to 68.70 miles with 5,277' of elevation gain. https://www.strava.com/activities/515703240

The power is now dipping into one bar, then periodically back up to two bars.

I'll probably nip out at some stage over the next day or so just to round the mileage up to 75 miles, and or 6,000' of elevation gain then call it a day on that charge.

I consider it quite an impressive figure given that the highest power setting has been used throughout each ride, and some of the climbs have been pretty significant.

The average mph hasn't been so bad either given the bikes gearing and elevation gain. 14.4mph, 8.8mph, 12mph and 14.1 mph. The 8.8mph was when I rode with a pedal bike rider.

 

[Artstu]

That's mind bogglingly good Eddie.

 

[EddiePJ]

I've been getting frustrated waiting for the battery level to drop.

Full review of the bike to follow at some stage over the next couple of weeks.

I quite like this photo that I took of the bike last Sunday morning in T/Wells.

 

[trex]

you will see E06 on the LCD, that's low battery voltage.

 

[anotherkiwi]

If you are sagging from two bars to one I think that you are at the end of useful battery power, when I get to that point I recharge. 110 km so less than 4.5 W/km isn't too bad.

 

[Emo Rider]

Way back on line #25 of this thread, the stated average speed, achiving this incredible range result, was 19mph. What this means to me:
1- The system was not engaged for almost all of the distance due to the cut off speed being 15.5 mph.
2- As the rider must have been incredibly fit to achive this, he didn't need an ebike in the first place.
3- The likelihood of the average ebike rider duplicating this result = 0

Perhaps this should have accompanied the original post.

"This consumpion figure was achived with factors that will in no way reflect the real consumption of average riders."

Or as the car companies put it

"These milage figures were achived under controled conditions. Your milage may (and always will be less) vary.

 

[anotherkiwi]

I have started my "limit max output" controller setting experiment and have set max Amps to 11 A. To my surprised this changed the motor's behaviour more than I expected. The cut off became quite brutal at 25 km/h in assistance level 5. The test was done on the flat I will have to test on the hills to see what happens there. As expected all the assistance levels are notched down as follows:
1 = 50 W enough to just about cancel the extra weight of the battery and motor
2 = 100W very nice around town on the flat
3 = 150 W " "
4 = 200 W enough for hills in town, riding against the wind, towing trailor
5 = 400 W big hills on the open road

 

[awol]

I got todays 10mile ride home down to 140w or 14wh/mile.
Maybe no crisps and the extra coffee did it and saved me about 40w.

 

[awol]

My mains power monitor thing tells me my battery takes around 180 watts to recharge for 10miles so that puts me way over average using pas level 3 and 4 at around 18w per mile?

I just figured out over this weekend that my charger uses just over 20w ontop of what it puts into the battery, so given my charges usually take 2 hours I can take 40wh off the power monitor figures which puts me at 14wh/mile with headwinds and 10wh/mile without so I am in the average range of 12wh/mile.
Back to the original post, did the rider notice any benefit having the motor or was the extra weight more of a disadvantage?
