I fitted my new Marathon Plus tyres today on a Cyclamatic Power Plus.
Not all plain sailing, but i thought i would share my experience to help others who may be thinking of doing this.
I did the front tyre first because it's a quick release and very easy to whip off.
I've heard these tyres are a pain in the bum to fit, so if i couldn't fit the front then i had no chance of doing the rear.
Almost as easy as fitting a normal tyre. A few things made it easier. These have been highlighted in other forums/threads:

1) Slightly inflating the inner tube helps with seating it on the rim without getting pinched, whilst levering the tyre into place.
2) zip tying the tyre to the rim in a couple of places saves it from popping off the rim as you lever it into place.
3) As you near levering the last section of tyre into place, it's best to lever very small sections at a time. 1 - 2 cms. You'll snap your levers otherwise.

The rear proved to be a little more taxing. It has the brake servo assembly on the left of the wheel and the power connector to the motor on the right.
The lead exiting the motor is about 8 inches long before terminating in a male/female connection, which then leads on to the controller. I assume this is so it is easier to remove the wheel. It has some shrink wrapping around it, but i wanted to leave this alone to preserve the integrity of the waterproofing.
I removed the wire cable to the brake servo lever and unscrewed the servo bracket holding it to the frame.
After releasing the main hub nuts, this allowed me to pull the wheel far enough out to remove the old tyre and tube and insert the new ones.
Procedure for fitting the tyre was then the same as the front one.
Hope this helps with anyone dreading fitting a new tyre or tube to this bike, as it's not as scary as it looks :)

I initially used the same technique but you don't NEED to use tyre levers.

The trick I found putting MPs on my small 16" wheels is to get the tyre bead right into the centre of the rim all the way round as you go. Keep squeezing the tyre together that is in the rim so it goes down into the centre and work the final bit of bead over the rim edge with your thumbs as you go. You will loose some skin!

It takes time but with patience it does work.

I guess if you use plastic levers its ok but on the smaller wheels I found they broke real quick and I then tried using steel ones :eek:

Not a good idea if you don't want to damage the rims.

Thank god for Schwalbe tyres :)
First time was interesting and strangely fun, but i wouldn't want to tackle the rear on a weekly basis.
Hope that didn't sound too rude :eek:

Tyre levers were not an option for me. You must have the strength of a bear jerrysimon!!!

PS not sure if it is correct, but are tyre levers more meant for getting tyres off rims than on ?

I actually don't have a lot of strength, although I play a lot of guitar :p

Getting the bead into the centre really helps and I was put onto this trick by a cycle repair guy, with years of experience. The trick is patience and methodically working the bead in the rim to the centre.

Yes, being ex-trade I rarely use levers, often not using them to remove a tyre either.

With the stiffness of MPs, it can be a good idea to tie or clamp the area into place that's opposite the valve hole, when that's first squeezed into the rim centre.
