EZee up the Whitby Abbey Cobbles.

I have seen posts about lack of traction on front hub motors. Just a post on my experience today.

I have an EZee front hub motor and 10ah battery, pedelec set up with no throttle but adjustable assist.

I have just ridden up three big steep climbs on the Yorkshire coast.

The first is a steep cobbled street at the side of the 100steps going up to Whitby Abbey. It is somewhere in the region of a 1 in 4 hill and has cobble stone surface. This was a tough climb, I had to move my weight right over the bars because of the steepness of the hill and also to keep traction. I have previously ridden this on a mountain bike some years ago and had to adopt a similar stance to keep from going over backwards when pedalling hard.

The second was the tamac road out of Robin Hoods Bay another steep climb about 1in 4

The third was a steep rocky climb up a track around 1in 6

All three hills were ridden up pedalling with motor assist working hard, the first and last needing quite a bit of my years of cycling skills to complete, I have done a lot of mountain biking in the past.

There was very little loss of traction however it was was mostly dry just the occasional damp patch.


So my question is would a rear hub have faired any better? I feel that I would have had to have had my weight over the front on whatever bike i was on and this may well have caused a loss of traction on the rear putting all the effort through one wheel.

Ps the whole ride was 26 miles from robin hoods bay down into whitby back to rhb up to Ravensar and back to rhb. Anyone who knows this part of the country will appreciate the long steady climbs out of these locations. Its about 5 miles uphill from rhb ravensar. I used 8.5amps from the battery and finished on the steep rocky climb. Impressed!

Rear hub motors come into their own when there's a tendency to wheelie up very steep slopes, this of course lifting a front drive from the ground losing traction. On my rear motor eZee I still have to throw my weight forward initially to control the wheelie when starting from a standstill up 1 in 4, but don't have to stay there once rolling.

As we both show though, among hub motor e-bikes the eZee models take some beating for really steep climbing.

For several years now the versatile eZee conversion kits have offered the option of a front or rear motor.

There is now the choice of the all new eZee Forza Mk2 with a rear motor for those who prefer it.

I know there are differing schools of thought on whether front or rear is best, but I think it comes down to horses for courses.

Very soon I'll be converting my full suspension mtb with a rear hub - I had been considering the MAC kit from cellman (Mac 500W Rear Kit (torque)) or the ezee kit - having read all the great reports on the ezee kit I'm leaning towards one of them. It's a fair chunk more expensive than the MAC kit but I think I've nearly made my mind up. I'd have one of the mk1 26" rear kits when they went on offer but they sold out - lets see what the mk2 kits are like :)

I'll be dropping you a few questions John when the mk2 kit launches - hope you don't mind :)

No problem Amigafan, look forward to hearing from you. The Mk2's are due to arrive Southampton next Tuesday, so we should have them in stock within a couple of weeks.

It is looking like we are going to be rather busy.
