I know when I was 14 I could get to well over 30mph on a slight down grade and a lot more when it was steeper. 80 mile rides on a bike made of old gas pipes (BSA Tour of Britain for those that can remember them) was a weekly occurance during the summer.

They will move the weight back again.

Totally agree on the road suspension forks make little difference but cycle tracks are an unknown variable, one man's rough track may be a billiard table to another. I do know there is a huge difference in forks including air forks, the Suntours on my Haibike are not in the same league as the...

Can you fit the battery on the front rack? If you move the bars forward you may be able to do as Fordulike says and move the saddle forwards. I don't know how much input you provide when climbing but be careful not to upset your riding position as this could have a negative impact on your input.

The more weight you can get on to the driving wheel the better. Do you know the actual angle and length of the steep part? You could set the bike up at the same angle with the front wheel on bathroom scales and measure the difference various mods make, then stick the scale under the rear wheel...

25-26 mph on a level road is not working me hard but as always this varies from person to person. I am quite happy and actually prefer riding and unpowered mtb but where I am living for large parts of the year is incredibly hilly. I usually average 10% climbing.

I don't know if it is something to do with the Bosch primary 2.5:1 reduction gearing, I don't really see how Yamaha with a 1:1 primary and possibly a1:1 secondary could detect this reliably enough to prevent customer complaints.

Magnet on crank arm, actually on end of pedals threads araldited into the Allen key hex on the end. The sensor is taken off from the standard position inside the chain stay and repositioned on the outside. I have done over 1000km in the alps with it like this with no problems.

Change up a gear and use a lower cadence then! My Yamaha provides useful extra input up to about 90 rpm plenty fast enough to do 30+mph on road bike gearing.

On gradients like that you need rear wheel drive, if it was a car you could reverse up! Even with rear wheel drive you will have to keep your weight on the front to keep the wheel on the ground. You can play with tyre width and compound all you want you will only improve the situation by a...

If you do that you get an error. On Yamaha mid drives you can reposition the sensor and fit a magnet to the cranks to activate the sensor. Speedo doesn't work correctly but I don't have a problem with that. Bosch motored bikes will not work by sensing cranks I am told but the above should work...

Nearly 50% of bikes round here are ebikes, mainly Haibike, KTM and Corratec. It is rather hilly here though, it's unusual for me to have less than 1000m of ascent on any ride.

Cut the brass inserts out of the old one and fit them into the new one.

I was saying make it wider.

Vivax assist are based just down the road from me in Wörgl.

I was thinking more of the width than the thickness.

If you are going to make one it looks like you could leave a little more 'meat' around the central screw and reduce the chance of a repeat problem.

Large parts of the Alps have flat valley floors where you can ride for miles with no hills. It is possible to follow the Inn river rising in Switzerland all the way through Austria and on into Germany where it joins the Danube without any hills at all. The track is frequented by all kinds of...

Yes I agree that was the point of my post, females generally think that it is only testosterone fuelled lunatics that overtake on the right so they creep down the kerb and get left hooked into a barrier by someone who can't see them. Always overtake on the right unless there is a good cycle...
