Which one would you suggest?

[roundtoit]

Hello, looking for some advice on a kit,I am in Perth Australia.
I am looking for a 'plug and play' type set up for commuting about 14km each way. Mostly flat, couple of little hills that I ride up at about 10kmh.
Will install kit on a 700cc flat bar road bike.
Looking for a kit as the ride is getting harder as I get older, funny that.
Top speed of around 30kmh would be heaps as ride is all on cycle paths.
Choice of kits :
Solar bike 350 w mini motor with 9ah lithium ion tube battery - on special at $950.00
Dillinger 250 w mini motor with 10ah lithium ion battery delivered for $750 approx.
I can take the charger to work and recharge there if need be.
Any thoughts, recommendations of other kits (with easy postage to Australia) appreciated.
Cheers

Either one should meet those very easy expectations.

Pop us with some links to the kits. Even though us yanks might still not know what their performance is like, it will make it easier for those from OZ to look at them.

Range should not be a problem even if your kits are 24v 10 ah, if you plan to ride mostly below 15 kph. If they are 36v 10 ah, for sure you have range for the ride.

Take a look at one of these Kits http://em3ev.com/store/index.php?route=product/product&path=36&product_id=138 with a Battery and Postage you might be paying a little extra but his kits are only $375 and the batterys start at $300 but the Quality and service is great and for a battery you could look at one of his frame mounted 36 or 46 volt batterys http://em3ev.com/store/index.php?route=product/category&path=35

If you read all the print on the kit page you can work out if you want a 12T 10T or 8T wind in the motor and for what you want a 10T with the 36Volt battery would be enough for your needs but i would reccomend the largest Frame mounted 36V he sells. i think you will find that Pauls batterys are a lot better quality than those kits your looking at aswell.

30kph would be near the limit for a 250 watt motor. A 350w motor would do it much better. I don't know anything about that brand kit, however.

In very general terms, the performance you want can be had by a 350 watt geared hub kit with a 36volt 10ah battery.

A jump up to a 500w motor opens a who new world of options, But is often too heavy for a road bike's frame, tires, and brakes to handle.

Thanks for the advice people, the motors from em3ev that have been recommended, do they run on 36 or 48 volts? Pricing is not too bay for em3ev stuff delivered to Perth, under $1100 Anyone in Australia know when GST kicks in on imported gear?
They dont look to be geared motors so does that mean that they will not free wheel very well? as I would like to still use my bike as a bike if you know what I mean.
Does 48v give alot more power or speed or both?
Sorry for dumb ass questions but am new to all this electricity stuff.
Cheers

They will run on eith 36 or 48 or 60 or 72 volts if you want but the higher the voltage the less Amps you can run through the motor, I have no experience with the 9C clone motors but have read quite a bit on them.

As for the Gst just make a note to Paul from EM3EV that if your purchase goes over $1000 you have to pay import duty tax, I ordered a BAttery which was over $1100 with delivery to NSW and didnt have to pay any extra because of Pauls understanding of this.

As for the cogging on those motors i wouldnt be too worried, Ive been riding around for the past month with my Crystalte H40 on my bike and no power and the only resistance i am getting is from the extra weight of the motor being 8kgs heavy, It doesnt spin as freely as a normal bike but even with my bad knee i still amnage to pedal 8km each way to the train station when i need to.

48volts will give you a little more power and Speed, As you increase the voltage the torque goes up a little also but more Volts = more Speed mainly, The more Amps you put into the motor the more power for up hills you will have.

As for sorry for the dumb ass Questions, They are not dumb but smart Questions for you to work out what sort of a system you need.
If you dont ask you dont get answered.

Cheers for all the help, I have gone with a 250 w kit from Dillenger, seems like a simple plug and play kit to get me started in e-biking. As my knowledge expands I will venture into more exotic setups, Will keep you posted on the kit.

Congrats on your 1st purchase, I hope you have a lot of fun with it and if you have any problems come back to this page and let us all know, Someone should be able to help you out with any issues you might have.

I'm riding the Dillinger kit on the freeway bike path north. It's more than good enough for what you're wanting to do. My 29er has loads of wind resistance and I'm averaging 30. It will surprise you, just make sure your brakes work well.
