Hey guys, I'm looking to invest in an electric kit real soon(summer is almost here in Toronto) and I'm seriously looking at the Ezee kit. I've read good things so far and was wondering if anyone would recommend this kit?

jethro56 

Many people recomend it. It was my second choice. I went with a 9C 2807 kit because if it's potential for modification. The ezee is a good kit also.

It's really good on hills. If you live in a hilly area, it'd be the one to go with or a 5305 crystalyte. Max speed is about 22 mph at 48v I think. Somewhere between 20 - 24 mph I think. The 2807 by comparison goes about 28 mph at 48v I think but the 2807 cannot climb hills like the Ezee motor can. Each motor has it's strengths and weaknesses.

I have purchased two of these kits from Justin at ebikes.ca. When I evaluate options, there are several characteristics of the eZee that make it my top choice:

- it is good quality
- it is significantly lighter than DD hubs
- despite the above it has high low-speed torque
- it freewheels so no drag when you aren't using the assist

I wanted to experiment with something else for the second conversion but these advantages led me to buying a second one.

Here are all the details of an evaluation and installation: https://www.bentrideronline.com/messa...173#post540173

Thanks for all the info guys. It sounds like this is a pretty solid kit. It's actually for my wife who has a condition which causes weakness in the legs. It's to assist her on moderate grade hills (although we're not in a hilly area) and on longer rides. She rides a trike so we'd be going with the 20" front wheel kit. We've had a Crystalyte kit before and it worked pretty well but it got rained on and crapped out on us at the end of last summer and we're wanting to upgrade to something a bit better and lighter and more water resistant.

Yeah, Ezee is a great kit and very convenient. If you get the total kit, the battery they include slips off of the rack so you can carry it into stores without worrying about getting it stolen.

I bet you could get that Crystalyte going with a sensorless controller, if it is just your Hall sensors that got wet. The universal controllers from bmsbattery.com are very cheap and run sensored or sensorless. I run the Crystalytes sensorless, as I've had similar Hall failures in wet conditions. No issues now.

Dave_mac, sounds like the crystalyte you got might be rusted out. Ebikes.ca offers a service to clean out the rust on the motors. That might be a better idea than just buying a whole new kit.

Hey Dave, have you seen this bike:

Anyone know about how water resistant this kit is if proper precautions are taken?

I recently got a second one with the eZee controller. The eZee controller itself appears to be more waterproof than the Infineon for what that is worth. You can do things like shrink sleeving connections, sealing with RTV Silicone and using the silicone dielectric grease in the contacts to improve the reliability of the connections. Cables should also be 'tied off' on either side of the connections so they are not stressed in use.

I actually trim all the leads to the length I want and when I re-terminate I use Amp Microfit connectors. They can be purchased with gold plated pins...

That PhantomX looks like fun, except that it doesn't appear to be much of a commuter bike.

Great tips, thanks!

I have had an EEZE kit which I have used for about 3 years now. (36V 10 amp) I commute every day 32 km round trip until the temperature goes below -4 C. I live in Ottawa Canada. I have 2 big hills on my commute. I pedal as much as I can but my knees are not the greatest so I need help on the inclines. Rain does not seem to affect it. The only problem I have, seems to be the cold. When I leave my battery out all day on the bike when it stays below 0 C the power will be cut back slightly on my way home.

Cold temps and batteries are a universal problem.

Hey everyone, I got the kit and installed it yesterday. I must say I'm very happy with it. It seems to be of very high quality and www.ebikes.ca have been really amazing to deal with. I would recommend this kit to anyone looking to convert their bike, so long as they've got an extra $1300 to invest.

rscamp

You get what you pay for. I hope you paid for a CA! I just did a test ride on eZee install #2. Both are high C 12s LiPo powered so 'nominal' voltage is 46V or so. With the 20" wind motor this gets it up to about 38km/h unregulated.

dave_mac

I agree, and it's obvious that the money was well spent with this kit.

Whats a CA? The kit I got is a 20" front wheel with 37v Life4PO battery and it's definitely quick enough for our applications.

CA = Cycle Analyst. One of the coolest ebike accessories around!

And here's a picture of it.

Oops, wrong picture. Here it is...

I see you need to zero your amps.

edcastrovalley

Yes, thanks. I better go do that...

What do you guys think of this setup https://cgi.ebay.ca/1000W-Hub-Motor-4...ht_9537wt_1139? I'm really happy with the eZee kit but I'm just curious really. I don't really trust eBay sellers from China because if you need to return the item you're pretty much screwed.
