Converting my bike... ecospeed vs crystalite?
Hey everyone, first post on the forum!
I have a Sun EZ1-SX recumbent bicycles (modded by the previous owner with 20" wheels... used to have a 16" front wheel), full fairing, and a few other addons... I got it specifically to convert to an electric setup.
I'll be purchasing an electric conversion kit pretty soon - and I've narrowed my choices down to ecospeed (ecospeed.net) or the crystalite Phoenix Racer (www.electricrider.com, and RSDistributers).
Although I've been riding bikes, and commute to school with my mountain bike... and also have a Ford Th!nk electric bike (which is so hard to get parts for - let alone trying to repair anything)... but I've been looking for something fast so I can go around town on bike than gasoline.
That being said, I'm pretty much a complete newb at fixing bikes... let alone trying to do my own wiring and whatnot to get a kit - so that's another reason why I've chosen these two.
Does anyone have experience with them?
After reading the thread on the crystalite - it seems that it may not be such a good choice? IE it seems like you need know-how to be able to work with the kit long-term (breaking spots and whatnot).
The crystalite is by far cheaper, higher e-power top speed (27 vs 25 for the 600W ecospeed), and I can get it far sooner. The Ecospeed is geared, and seems a better system and is FAR lighter... but a lot more expensive and it would take 6 weeks to get the ecospeed 600W.
The weight of the crystalite is about 68 pounds (which is including the wheel around the hub)... and my other concern is that this would be too much weight on the recumbent (I weigh about 125 myself).
Can I get any advice on which system would be more appropriate for me? I would really appreciate it!
I live in a very hilly area... commute to school is very short - 1 mile... but to get around town is longer
(and I'll be happy to report back how the system is!)
There is another option that you may not be aware of, the Electro Cycle E-4 Kit for EZ-1 and EZ-3 Recumbent Cycles. This kit has been designed for the EZ-1 and EZ-3.
As for the other 2 oprions when I read you first post the last line about living in a hilly area made the decision in my mind. I also live in a hilly area and have several e-bikes and e-trikes. All of them have now been converted to use some type of gearing due to the hills in my area. Using gears has helped my range, top speed, and hill climbing on each bike/trike.
I have come to the conclusion gears are needed for hilly areas. None of my bikes/trikes at this point have large motors. The largest motor I have used is 500-watts, with one bike running a 400-watt motor with a top speed of 23 MPH. Again I think the gears help the smaller motors do the bigger job of hill climbing, with good top speed and longer range.
Keep up informed, we all like to hear from others experiences with their EVs.
My setup is very homemade. I took the guts from a Chinies X-Treme X-500 36-volt electric scooter and after some modifications to my EZ-3 created an electric trike. Here are some photos of my EZ-3.
Here is where the motor and 3-speed hub are housed. The blocks of wood holding the jackshaft have bearings inside so the jackshaft spins free.
As you can see this is a real Rube Goldgerg, home brew. I also have 2 batteries packs inside the box each of them are 36-volt 12-AH. When I built this trike 3 years ago I was very new to EVs and therefore not the best EV designer. With that said the trike preforms surprizingly well. With a top speed of 27 MPH on level ground and a range of about 24 miles, 12 miles on each battery pack. Acceleration is good but not great because of the weight of the trike, the gears, 3-speed hub, give it more than enough power for hills. It was a great project and I learned a great deal about EVs. My next bike will be much different, it will still use gears and I am thinking about using the Electro Cycle E-4. I think it will give the best bang for the buck.
Here is a computer modified picture of my next project.
I bought the 600 W from Ecospeed and i can't recommend Brent and the product enough. He is great, the product is fantastic. It is very powerful. I have a Sun EZ Rider Recumbent with suspension. I now have two of them as well as an EZ Sport. I only have one Ecospeed.
If hills are an issue and power is an issue, Ecospeed is the way to go. I was a newbie as well and learned a lot. BionX is another choice although the power will be less. The Ecospeed just takes off. The only issue is that it is slightly noisey as compared to the BionX. My wife has the BionX 350 and she loves it. We use both bikes in the country on big hills. On really very steep hills only the Ecospeed can manage because of the gearing. Don't buy the BionX from NYCewheels. I had a very bad experience with them. But BionX themselves are excellent and the product is great. Tough choice but it depends on the riding you will be doing and if you care more about power vs cruising. Hope this helps.
Keep us posted. Be careful not to damage the batteries with the clamps. You may want to put a piece of wood between the clamps and the batteries. About what does a rig like that cost?
I decided on Crystalyte and I had my first eBike ride today ... great fun!
My DIY ride is at http://web.mac.com/pguild8/iWeb/pdg%20iFlick/eBike.html
I was curious to know why the photos you posted are in mirror image ( backwards)?
My Bicycle Pages
Are those lead acid batteries?
I use a wildernes energy on my homebuilt and I can get 20 mph with a 36 volt set up.
I also have a sun ez1 sx and I am not sure a hub moter would fit in the drop outs as the axle is quite large.
I do wish you the best though. I have some pics of my home built here. http://imgsrc.ru/williammcc1/a226067.html
Hi as well!
My first post also...
I too have just received my EcoSpeed......I will mount this on the Sun X-3 SX...If you go to EcoSpeeds home page ...go to Products open to "EMD" and scrol to the very bottom this is my bike.
I have a Lipo Lith batt 36Volt 15 AH from "Ping".
What might I need to know about the install of the motor and adj of chain?
Pic of motor on bottom of Product to EMD and to the vary bottom hit "detail"
Might you forward pics to me...can't see these...I too have a delta trike Sun X-3 SX http://www.ecospeed.com/prodemdu.html (scroll to Very bottom to see my bike)
I am just putting this together....
Any insight to pit falls?
Thank you very much!
