Which e-bike for powerful/fast unassisted use and towing a luggage trailer?

[Richdog]

Hi guys, i've just relocated to Switzerland such is the public transport and convenience of the city I live in that there is no need whatsoever for a car. Now, I am planning to buy a cheap "regular" bike for exercise/tootling around on... but I also want to invest in the most powerful e-bike possible capable of going long (around 30 miles or more) distances unassisted on a single charge, and capable of towing (with assistance when necessary) a shopping/luggage trailer like this AVENIR MULE BICYCLE LUGGAGE TRAILER :: £79.99 :: BIKE TRAILERS :: Trailers :: Southwater Cycles

Not only will this help me carry loads to friends houses etc, but it will make shopping much mor eco friendly and allow me to carry much more back up hills etc.

So in summary what i'm looking for is:

• The most powerful/fastest motor possible capable of unassisted travel on even roads, and capable of pulling a trolley assisted without too much hassle
• Reliable
• Looks reasonable and sleek
  
  Any suggestions please chaps?

From what I remember of Switzerland a UK hub motor won't do the trick on the hills and the Panasonic motor won't work unassisted, you will probably need something designed for the US market.
Problem then is getting 30 miles on Swiss hills without putting in any effort, that's one hell of a battery.

You can read quite a lot about it on the ExtraEnergy site Keith.

It's one of the very few bikes that can come anywhere near what Richdog wants, and it's Swiss so he's in the right place to buy one.

Richdog, I do plenty of heavy trailer load hauling when necessary, but my advice is to only use a trailer when it's essential, using large panniers whenever possible instead, since trailers bring various disadvantages.

The trailer weight to be hauled is far greater than a pannier set.

Two trailer wheels doubles the tyre drag of the bike.

I've found range with a trailer often drops by over a third from normal due to the above factors.

The bike handling and braking is far worse with a trailer.

Richdog, if money is no object and you want the highest powered e-bike available you can't go past the "el-cycle". This is the world's most powerful production e-bike and has a top speed of 97kph. It is entirely European designed and hand built in Austria. The company which builds them only makes a maximum of 50 cycles per year and each cycle is custom assembled from the highest quality materials.
The el-cycle has no problem at all of towing a trailer up even the steepest hills carrying a heavy load due to the 400amps peak discharge capability of the 36volt LiFePO4 battery which powers this e-bike.

You can check the specifications out on the manufacturer's website at-

Yes, but we've seen pictures of your trailer, with a large garden shed and about half a mile of bubble wrap loaded onto it - hardly surprising that the range is somewhat compromised!

Most of the loads aren't like that Rog.

Even an empty two wheel trailer cuts range considerably and i only use a trailer when it's absolutely necessary. Below is a much better way to carry a fair amount from the speed and handling point of view:

Did it appear that I was being entirely serious? Shirley not!

No I knew you were teasing Rog, but I thought it a chance to illustrate how big panniers plus a flat load platform can enable carrying as much as many trailers, leaving out the extra tyre drag. Personally I wouldn't use the average commercial bike trailer since most carry no more than a good pannier/platform setup can cope with.

If it's as powerful as you say then with the size of battery in the picture the range will be about 5 miles.

was thinking the same think..........looks extremely small. Was expecting to see a beast like the E Rocket! lol

Another rather small battery (and from the company website still appears to be NiCd) so might get Richdog up one hill.
One of these with pedals on might be what he's looking for.

Heinzmann do some kit motors that are more powerful than UK-legal, but you have to choose either high speed, or high torque for towing and hill climbing.

Maybe if you put a high-speed motor on the front wheel, and a high-torque one on the back, you'd be approaching Richdog's original wish list... but he'd definitely need the trailer for the shopping, because the panniers would be full of batteries.

Looking at this page
Just Ernst's 2008 el-cycle city
they quote a top speed of 15mph and a range of 40 miles. They add that the prototype set a record of 97kmph but they don't say what the range of the prototype was.

The "el-cycle" from Austria is supplied in two versions.
First version is the "street legal" version which is speed limited/governed to 30kph.
Second version is what the manufacturer calls the "off road" version which is speed limited/governed to 60kph.
Both models are programmed not to exceed the maximum speed through the programmable motor controller.
End of 2009 the el-cycle will have the option of being fitted with the latest model "high energy density (HED)" LiFePO4 battery which will increase battery capacity and range per charge by 20%-40% for the same phsical size battery pack. This battery is in the final testing stages now.
As mentioned with no motor speed limiting and allowing full battery voltage to reach the modified 5kW Crystalite motor the bike will reach speeds of up to 97kph.

Maybe a kit. The real problem will be getting full value out of a Lithium battery. It may die before you get a decent number of charge cycles. If you use it once a week or less, leaving it half discharged in the fridge may help, so long as you warm it up before use.

There is not much chance of the battery dieing or risk involved when it is backed by 3years/3000 cycles factory warranty. Also the cells have minimal self discharge and a fully charged cell will still have 80% of its original capacity after 2 years so even if a cell isn't used for a few weeks the miniscule amout of self discharge would not even be noticed.
