Help please need advice

[Todd]

Hi all,

Could I ask for advice please, I'm looking for a 500w folding bike that has a high capacity battery
20ah, it would need to be able to pull a small trailer for camping, and used also for trips around London.

Any help is much appreciated

Big motors and big batteries are rare on folders.

The nearest spec ready made bike I can think of is the Volt Metro, which has the option of a 16ah battery.

Building your own might work, but mounting 20ah of battery on a folder will not be easy.

Carrying a spare battery to give the capacity you need would be simpler.

your best bet is the woosh zephyr-B that is folding and has the strong 8-Fun BPM motor to haul load.
For battery capacity, get a spare 36V 15AH battery from woosh and ask them to make for you a lead to link the two batteries together. You'll get 25AH.

Ezee Quando has a 20 amp controller. I'm sure they can do something with the extra battery too.

I'd second the eZee Quando folder suggestion, it will accept a single battery of 21 Ah or 28 Ah capacity, so plenty for the desired range. The 21 Ah is a stock item but the 28 Ah is a special order. The Quando has plenty of power for trailer pulling as you see here on a 14% hill:

And another view:

Thank you for your advice, it's very helpful, would I be able to get the eZee Quando with a 500w moter ? For speed,

I believe Ezee bikes only come with their own motor.

But don't get too hung up on watt ratings, they often don't mean a great deal.

The Ezee motor is known to be pokey and has the benefit of being stamped as road legal.

Of course, the guy to ask is Cyclezee in the UK.

He posts on here and is always helpful.

Hi Todd,

Following on from from the others who have posted about the eZee Quando, it has a 250w motor, not 500w.
Speed is limited to 25 Km/h.
The controller is 20amp.
Battery capacities are from 11 to 28Ah.
The battery capacity can be increased further with the dual battery option which adds another 15Ah to making 43Ah possible.

You can see the full specification on our website via this link http://cyclezee.com/ezee-quando.html

In case anybody is confused about power, the raring of the motor 250w/500w has nothing to do with how much power you will get from it. A 20 amp controller with a 36v battery will allow about 800w to the motor, which means about 600w of motive power at about 15 mph or 400w on not too steep hills. The Ezee motor won't overheat under those conditions, so you can make up your own rating. The main point is that the manufacturer says it's 250w, so it's legal.

On another point, somebody said that they wanted a 500w motor to go faster. The power rating has nothing to do with speed either. You need high motive power to reach high speed, but many motors, 500w or otherwise, have a speed limited by the design of their winding. It's the maximum RPM of the motor that's important if you want speed.

Cyclezee as a supplier would be unwilling to detail this, but the 36 volt battery on the Quando coupled with the 20 amp controller enables around 720 watts consumption by the eZee motor. The net power into the road when under high load as when hill climbing can reach around 500 watts at around 8 to 9 mph. That's what makes it such a good trailer puller.

This page on my website show how it served me in that capacity for years.

Thanks for your reply, is it possible to un-restrict the motor, life cycles have said they put a un-restrict button for off road use. Also do you keep them in stock,
What would roughly be the range of a 20ah battery 15mph reasonabley flat roads. Many thanks Todd
