I suppose it was inevitable that one day, a center-drive machine would join the collection, but choosing the most suitable machine was a rather drawn out affair. The machine needed to be able to cope with trail riding, so the first requirement was disc brakes all round. Many of the trails I ride are limestone hardpack with the top layer 3 mm down to dust, add a little rainwater, and the grinding paste created will quickly wear rims to the point where replacement is needed, not a cheap job. The machine also needed to have enough range for 5-6 hour rides of around 40 miles. This would usually mean climbing to 900 feet ASL, possibly twice on the same ride.

The first machine that caught my eye was the Gepida Sirmium with a Yamaha center-drive. I had a very good look at this machine at Presteigne. Clearly designed for roughing it, I was surprised to find rim brakes front and rear. Although the machine could be fitted with a disc front brake, It was the very small 8.5 ah battery which finally ruled it out. Even with a 2nd battery on board, I doubt it would last the distance.

At the time, I had a 36 volt center-drive as my dream machine, so I was mildly optimistic when the German made Daum pedelec appeared in AtoB. The let-down was the main battery occupying the place where my 2nd battery would go, add to this the rim brakes and that was another contender out of the picture.

Another very attractive machine to go under the microscope was the Raleigh Leeds Sport, unfortunately it was not available in Britain, and shipping costs from Europe would have made it prohibitively expensive, particularly as it's Kalkhoff equivalent had been reduced to £1895 delivered.

The final decision was made very quickly with the imminent availability of the BMZ 18 ah battery, which will fit almost all Panasonic powered machines. And so it was, two days later, despite the best efforts of the 'dynamite boys', the Kalkhoff Sahel Pro disc arrived unscathed.

Drive-side


Anchor-side.


Solid alloy Pletscher side-stand bolted directly to the die-cast drop-outs.


DT Swiss eyeletted rims and incredibly tough composite blade style mudguards


Fully assembled apart from the pedals, all that was needed was to swivel the handlebars into position. With the battery charging, seat and handlebar heights were adjusted, a speedo fitted and calibrated and the 'ting' bell replaced with a traditional 'ding-a-ling'. As it was almost tea-time when the five lights went out on the battery, the first ride was postponed until the next morning, and what an eye-opener it was.

To be continued.................

I've long considered the Panasonic unit as the best for off road use Blew it, and yours looks like a great choice,
ideal for the job in every respect.

I'm looking forward to your riding reports.

Very nice ! just when you think you wouldn't buy another bike for a few years somebody goes and posts a picture of their new pride and joy :mad:
Enjoy....i am sure you will,especially with the 18a battery.

I wanted something similar and I did consider the pro sahel disc but the price they quoted was I think £2395 - way over the top for me. 50 cycles were a bit evasive about if and when they were in stock too, so I went for the Emotion Sport Max at £1850. I wasn't keen on the 26 inch wheels but probably better for you for off road. The alfine is better off road too and you got it all at a reasonable cost. 50 cycles might have got more business on this bike if the price at been set at a reasonable level to begin with. I would probably have gone for one but then I am very happy with the Sport Max.

I also like this bike, as I am in mind to get a Panasonic as well after my experience recently with the swiss Flyer......Oh Lordy!:p

I see that Kalkhoff have dropped the price of PC S by £300 or so and the Sahel as well. Does that mean some new exciting bikes on the way I wonder?

Good luck with the new bike Bob! I must say it looks Brilliant, much better in your pics then on very poor website IMO..... I just wish they did an S model:D

Along with the Pro Connect S, this is one of my favourite Kalkhoff ebikes. Great looks and excellent ride quality. We had a gentleman in for a test ride today who'd tried an e-motion, daum, giant and ezee recently and he was bowled over by the Sahel Pro this afternoon.

The Sahel Comp is very similar - differences being hydraulic rim rather than disc brakes and Brooks saddle and handgrips. It looks very fetching and has had pride of place in our shop window for a while now. I think they will be snapped up quickly now the price has dropped down to £1750.

The initial high price was due in part to the weak pound earlier this year and relative scarcity at that time.

Thanks for the review and superb photography Blew it, you've settled on one of the best there.

Lovely looking bike, reminds me a lot of the flyer s. I believe that next year there will be a high speed model which would have been a real contender for me it it had been available now.

Great looking bike apart from the battery,why do they try and make it stand out so much.
It's because the battery and unit are designed as an integrated pair, the unit being natural alloy colour means
the battery follows fairly closely. Giant and Flyer with the similar original unit almost always had their bikes
also in silver so the unit and battery didn't stand out. Yamaha in contrast make their similar unit and battery in
black.

It's always a problem, I remember when eZee had their bikes and batteries in silver, black and a range of primary
colours at one time, very nice too until it came to battery replacement time. Then it was a nightmare for suppliers
to maintain a full range of coloured batteries in stock fresh, so it inevitably ended up a choice of one, silver.

Don't forget the emotion are in black too and very nice they look. Of course I will have a problem with battery replacements especially if I want to go with the 18Ah version.

I am sure a local car body shop could prepare and spray it any colour you want.....

You can easily do it yourself as long as you use plastic primer. I spayed some plastic the other day and it looks good. Anyway we are still waiting for the prices for the 18Ah and judging by the usual 50 cycles pricing they will start at £999 in the summer and end up at £650 by the autumn;)

Yes, they do tend to do that dont they:D .......Plus have never really trusted them after Tillsons rear wheel saga. But definitely some interesting product coming out from them.....

Part two:

Swindon Borough Council, although failing to transform the drab and dreary Town Centre, has excelled in providing over fifty miles of segregated safe cycling routes throughout the Borough. The Sahel made short work of the ride down the East side of Swindon, on-route to my favourite tea-urn, Coate Water Country Park.

The Sahel was supplied with an 18T sprocket on the Alfine 8 speed hub ( 26" wheels). I was very surprised to find the Panasonic assisted up to 17 mph, although the high cadence was unsustainable. The Panasonic drive is so quiet, it is sometimes difficult to know whether it's assisting or not, especially as this machine is so easy to pedal with the power switched off. I tried this again on a slight up-slope and found it was definately assisting to 17 mph. (confirmed by GPS). Before today's ride started, it took twenty minutes to fit a 16T sprocket to the Alfine hub. An 11T motor sprocket was to hand, but was not fitted as I prefer to make one change at a time. As it turned out, all that was needed was the change to a 16T on the hub. The cadence is now quite leisurely at 15 mph in top gear, spin the pedals a little faster and the Sahel surges up to 19 mph (confirmed by GPS), at which point the assist is tapering down .


Disc brakes require precise re-location of the wheel after removal, hence the use of vertical drop-outs, chain tension is looked after by the Shimano CT-S500.


For those that ride at night, Sahel has the Alfine hub dynamo feeding the Busch & Muller LUMOTEC IQ headlight, automatic switch-on at dusk and stand-light feature.


Wide handlebars with a slight back-sweep provide a comfortable wrist position. The ergonomic lock-on grips give plenty of support for the palms, a small hole in the underside giving access to the clamping screws. No faffing about with rubber solution here. Removeable rubber bungs in the grips allow easy fitting of the Mirrycle bar-end mirror. The medium size, 50cm frame is spot on for my 5' 10", 33" inside leg to the ground.

Gubbins!


Beware! Sahel has rigid front forks. I had intended to fit suspension forks, but after riding Sahel along some very bumpy tracks, I have decided against this. The fact is, after three years of trail riding, my wrists, elbows and shoulders are well hardened to the thuds delivered up through the frame, and anyway, I think it would spoil the look of the machine.



The supplied pedals had to be replaced. One of the sole treads on my Northwave Mission walk 'n' ride shoes was resting directly on the alloy pedal hub, resulting in my feet constantly swivelling about. And no!, much as I love my E-bikes, I have no desire to increase the attachment further by clipping-in. Changing to a pair of MKS MT lites, which I knew were compatible with my shoes solved the problem.

The tea-break at Coate Water had barely started when another rider stopped to join me, riding a Cyclamatic. Almost an hour was spent comparing machines and sharing experiences. Two more old buds arrived which kept the fat-chewing session going even longer. Eventually, I managed to escape and continued the ride up to Old Town and pick up Route 45 down the West side of Swindon.

To be continued..............................

Sorry to hear that. If it's any consolation, the staff involved in that saga have since moved on. We're not perfect though, of course, as the slight hitch with Aldby's chain demonstrates - we'll look into that on Monday morning.

I would not want to risk making a £1800+ ebike look even worse,paint spraying does require some technique,an expensive electric bike is not an item i would choose to practise on.

Yes I am going spray my electric bike silver to match the battery :eek:

That's one way to make it less attractive to thieves. ;)

Spraying a battery case is practical though. Below is a photo of a standard eZee battery case and one I
lengthened for more cells and sprayed shown alongside:
