When out and about with Sahel a few weeks ago, I had a cup of tea with a cyclamatic rider. We spent some time comparing the two machines, always bearing in mind the price difference. There is really only one weakness in the Cyclamatic, the front forks, functional but a bit naff. Yes, they will take the thump out of a speed hump but, the brake posts are mounted on flimsy steel pressings welded to the legs, when applying the brakes the whole lot flexes alarmingly. The owner of the Cyclamatic was very pleased with his machine, but a bit miffed when I explained he could have purchased it a lot cheaper if he had waited for a discount voucher, he paid the full £500!!.
The entry level Izip machines are also fitted with the same forks, as was a machine I customized early this year. In the case of that machine the forks were replaced with far better Sun-Tours for £40. Other than that minor niggle with the front forks, I would say the cyclamatic compares very favourably in price and quality with the Powacycle Salisbury, probably it's nearest comparable machine.
Regarding the BMZ 18ah battery.
Please remember, only a limited number of these batteries will be available to existing customers wishing to upgrade. I ordered mine as soon as 50cycles put them on their website, also, considering I'm getting precious little interest on my savings I paid the full price up front. At least I'll avoid the 2.5% VAT increase.
