250 watt is it a myth?

Thanks again Andy88, I had a look online at the Freego Bafang Max Drive and also the Bottecchia versions, but they were based on a reg MTB top bar frame.
That's not right. Freego have two versions of the same bike. One is a stepthrough. Their listings are a bit confusing. I had to look twice. I know they do one because it's in our local shop.

Edit: It looks like you found it then.

This should be of interest, here's some Strava stats comparing the development Juicy bike with the Roller motor system compared to my old classic Bosch bike.
I did my first run on the Juicy,and second run back up on my bike, despite being tired from the first run I was 2:24 faster on my bike, I didn't find the Juicy bike enjoyable to ride in the way my bike is.

I'm surprised your ride hasn't been reported by the Strava mafia! They are on to me within minutes if I post any electric bike times there - ie significantly faster than my usual attempts!

Although looking again I notice these segments have only been ridden by a couple of people.

Yes it's listed as an E-bike ride, so the segments you see are made by me for e-bike riders.
Listing as a normal ride looks like this :oops: :)

What I don't understand though is what you do when you ride over a segment which is not one of your own? Is there some way of marking a ride so it doesn't show up on all the segments you ride over? I've given up putting GPS records of ebike rides there - I just put the time and distance so its at least included in my annual totals etc.

When you upload your ride in the drop down activity box choose e-bike ride rather than ride, then it will be correctly listed and won't trigger the normal ride segments ;) :)

If you look at my Strava you'll see nearly all my cycling is e-bike, and the cycling totals still work.

Excellent, thank you, I haven't seen that option before - maybe its newish. Wish I hadn't deleted those rides now - maybe I still have them on Garmin Connect and can restore them.

Can you guys tell me how easy it is changing gear and maintaining derailleur gears? Looking at IGH but so restrictive on bike choice, looking to convert to BBS02 or BPM. Is Deore the best? Easiest?

I forget how long the e-bike category has been there now, a year or so? perhaps Phill can remember.
I used to make all my rides private shortly after sharing them. When the e-bike catergory was introduced I asked Strava support to change all my private rides to e-bike and make them public. It's a big improvement for all us e-bikers now.

It's debatable Andy, which model of derailleur is best but I know many bikes, both manually-powered and electric, make do with gearsets from the lower reaches of Shimano's range and present few problems. Frankly, you probably wouldn't gain a great deal by ignoring the budget end in favour of the high-end products but your wallet would be considerably lighter.

As to their efficacy and ease of use, I find them reliable if set up correctly and very simple to use. I like internal hub gears too but it wouldn't concern me whether the best-riding bike on test had one system or the other, especially as most people don't need to use many of the gears on electrically-assisted bikes anyway.

I would agree with oldtom. The modern derailleurs have a lot going for them. 1They now have click positioning and this is as definite as the hub gears.. each click on the control lever switches one position on the rear cassette, the 1970s types with lever arms were more prone to skipping.
2They have a wider ratio of speeds available than hubs.
3 They are lighter in weight
4 They are more efficient.
5 gear changes when the chain is moving is very useful going up hills

Against
1. Chain must be moving so bad for changing gear if forced to unplanned stop . Hub gears have a distinct advantage here.
2 cleaning .. more exposed cogs more places for muck to hide
3. More prone to damage if bike falls on the RHS.
4 more chain wear the sideways force is greater and causes wear. But chains are cheap
5 more wear on the exposed cogs but replacing cassettes are not expensive either.
6 Hub gears are very reliableand robust but not user fixable

Andy, if you are anything like me, it is likely you will be kicking your clogs before any of these wear are major concerns. See the postings about a persons complaint that they had to stop peddling in order to change gears on a hub gear. After 1 weeks use the operation becomes automatic.

To put these wear problem in context. I still have the same cogs on a 1975 viscount touring bike, used extensively for 4 years and intermittently since, the same hub gear on a Moulton dating from 1966 and have had a derailleur hanger replaced once and the chain replaced once on a small wheeled urban mover electric bike 2007, which was in daily use for 8 years . Cost of replacement in a Halfords was I think 50 Euro
