Why does a Pedelec cut out at 15.5mph?

[Artstu]

Its also worth noting, that even with the 15.5mph cut off, on a relatively straight commute... I'm faster on a legal eBike than I am on my road racing bike.

There is a thread here, that you might not have seen Job100.

http://www.pedelecs.co.uk/forum/threads/how-much-faster-by-ebike.16505/page-2

Summary, was... the 15.5mph cut off is enough to make a ride faster, or easier for even a fit cyclist in a hilly area. If the ride had more stopping and starting the difference would be even greater, because its all the time spent below the cut off, and on the hills where you save the time and effort.

In essence it made me realise the cut off is adequate for on and off road.

It's worth pointing out that that was done on roads that were either going uphill or downhill steeply. Conditions where the cut-out has much less of an impact than on flatter roads.

I challenge you you repeat the test on a flatter commute now, perhaps you could do an extended flatter circuit on your new commute?

Thanks.

I'm looking to compare it v the Haibike Fat Six. So I'd want a blow by blow comparison. I'm interested, to a point, in personal opinion, but I like to review objective data as well, that's my start point really.

I can't quite understand why a company would not want to advertise their product better on their own website?

Use the forum bike finder both are detailed there:

What happens on a cloudy day and there is no breeze to turn the electricity windmills?

Battery bank will last a few days, then same as everyone else, mains. Not often that mains is required

Sherman, a forum member has one, and I'm sure that he would be more than happy to answer questions that you might have. http://www.pedelecs.co.uk/forum/threads/how-many-people-are-using-there-e-bike-off-road.15780/page-52#post-277752

Yes, I'm happy to answer any questions regarding the bike

Also, all technical info is available at KTM's website, here's the: link for KTM Macina Freeze CX5 2016 Model

edit: some details seem to be missing. As the bike looks pretty much the same as 2015 I assume the stem is 120mm long and fork travel is 80mm.

Differences to 2015 model: tires 4.8" tires instead of 4.00", rear hub 177mm (170mm), new 11-speed XT drive train 11-42 (old 10spd, 11-36), and of course the 2016 Bosch motor and 500Wh battery.

Not really true... most of the commute was through Huddersfield and along the relatively flat A62 to Marsden.

My commute to work is currently a 600m walk (we've moved the offices to Huddersfield now) so I'm not sure even a motorbike could save me 15 minutes.

But once we get some demo eBikes in, I'll do some rides around here that are typical commutes to compare and contrast the results.

After my first couple of rides around town with my new "gearbox" I have noticed that I no longer feel the cut-out. That kind of on again off again sensation where you are constantly just around 25 kph. One of the reasons is that with the 48 tooth up front I am now regularly at +26 kph on the flat without really trying hard.

The cut out on mine is smooth too. It just requires at least twice of the effort to ride at 17 mph, or as I have to do, back off a little and put hardly any effort in below the cut-off.

My bike just isn't suitable for trying to ride above the cut-off on the flat. A gentle slope makes the world of difference though. I take the hilly minor roads to avoid flatter roads where possible.

OK so I just did a quick there and back again road test. Went down to see if the frontier is secure! Short answer: nope

14 km in 30 minutes is 28 kph average in my book, a 1.4 kph increase over the previous 42 tooth cog BUT:
- Battery not fully charged
- max speed set to 25 kph
- Windy, head wind both there and back, couldn't stay above 40 kph without pedalling on the descent on the way home - that is my usual free-wheeling speed!
- Chain should have been lubed last week...
I give that a "real world test" stamp of approval.

Having the right gears is very important (duh! moment but remember I have been away from bikes for years)! The SiS front cog makes the SiS indexed free-wheel work much better despite a very dry chain. Quiet, smooth changes both up and down, better precision over the whole 7 speeds. No more heel strike on the chain stay with the Shimano crank on the drive side! Better chain tension with the larger cog, it didn't ever try to jump off.
