After a year of pouring over this and other forums trying to find the right kit for my needs I finally purchased a kit. After reading Terry's offer of the free shipping and the combo price on the Aotema motor, controller, 36v10ah LiFePo battery and Dogman's review of the kit as well as many other positive comments on this forum I decided this was the kit to try and I have to say I am VERY glad I did.

A little background. A little over a year ago I heard about a cycle shop in my town that was selling an e-bike kit so I went over to check it out. He was selling Bionx kits and he had a PL-350 set up on a test bike. I rode it and thought it was one of the greatest things ever. The only thing holding me back was the price. For those of you that don't know, the PL-350 is about $1,700 (or a cool thou over the cost of Terry's kit). Two of the big selling points of the bionx system is the weight and the fact that it has regen. However, the cost benefit for that was a little daunting. Even when gas was $4 a gallon it would have taken me a LONG TIME for that kit to recoup the expense. However, the e-bike bug had certainly bit me hard and I kept looking at other kits and options.

I had a bike already that I was committed to putting the kit on. It is a Trek OCLV carbon fiber MTB and had Manitou front alloy suspension forks. I wanted a rear hub motor and was looking seriously at the BMC from EV tech. Then I realized my rear dropouts were aluminum. Easier to replace forks than rear dropouts so a front hub it was going to be. I wasn't interested in speed above 22 mph or range much beyond 10 miles, but I did want to be able to get up the hills on the way up to my house. Disc brakes didn't matter to me either as the Trek has good cantilever brakes on it that should be fine for the speeds I wanted. Then I started reading Dogman's review of Terry's kit and it seemed like if the kit was working good enough for Dogman's commute it should be fine for mine as I only have a 3 mile commute each way. Like Dogman's, my ride to my work is pretty much all DH, but the ride home is all UH. I will post some grade info later.

I decided to order Terry's kit. The kit arrived in a reasonable amount of time. I ordered the kit on the seventh and it arrived on the fourteenth. Kit arrived in good shape. The front wheel is heavy, 15lbs, but the quality of the wheel build is nice and and it was true. There was no documentation at all and I was glad that I knew where all the good e-bike info was on ES! The controller is a nice looking piece of kit with a gloss black finish a rocker type power switch and two indicator lights. A red light that indicates the power is on and a green light that means something else. Sometimes it is solid and sometimes it blinks. Not sure what the meaning of the two are. I have e-mailed Terry about this and he is checking on it. As this is my first kit I don't have a great deal of knowledge of the different controllers out there, but this one looks nice (dare I say a little sexy) and has a good solid feel to it. The kit does come with a nice little goodie bag with zip-ties (way more than I needed and in various sizes for different applications), a spoke wrench, a seat post clamp, and some heat shrink tubing. A nice touch that will save more than a few people that buy this kit a trip to the bike/hardware store. The fact that the battery has the andersons and the controller has bullets(as mentioned by another poster in Dogman's thread) seemed a little odd to me a first as well and then i saw the extra andersons and realized that it was done that way to allow for custom installation to length. I didn't have any experience with anderson connectors so I had to do a little research, but I was able to find all the info I needed here: http://www.westmountainradio.com/supportrr.htm and was on my way.

The battery is in a Topeak bag on their nifty slide and lock rack.

I wanted to be able to easily take the battery with me if I had to lock the bike outside somewhere for an extended amount of time. The 10ah battery fits in this bag wonderfully and still gives me enough room to store a tool kit and all the stuff I carry around with me during the day like wallet, cell phone etc., with room to spare and then if that isn't enough there's always the paniers. I thought all the connectors were on wires that were a good length, except the leads coming from the battery. They could be a little longer. Because of the way the shrink is on the battery the leads are in an awkward position and are just a little short. Would be great if they were about 4" longer. The wire from the controller to the motor was the only one that I thought was a little long, but I was mounting in the frame of the bike. If I had wanted to put it on the back it probably would have been just right. Nonetheless, I just folded the wire up a little and used a bit of the included heat shrink and voila, perfect length! After getting everything together a quick weigh in showed the bike to weigh 50.2lbs. Heavier than I had hoped, but I think that is still pretty light compared to what it could have been with SLA's!

So I have taken it to work the past two days (12 miles total) and it has performed brilliantly and is exactly what I wanted. It gets me up my hills great. It gets me out in the open for awhile everyday, and it hasn't changed the feel of my bicycle significantly. Normally by car it takes me ten minutes each way to work and back. By bicycle it would take about 35 minutes total. It would take me about 12 minutes there and 23 minutes home. Today I was a little rushed to get to work and get back home so I pushed pretty hard in both directions. Even stopping at two full red lights and at three pedestrian crosswalks my round trip ride today was 22 minutes and I would say that was probably 10 minutes there and 12 minutes back. I'm impressed. :D

The motor is very quiet. My main concern was buying a kit I couldn't ride before I bought it. I didn't want to spend that much money on something that would still struggle to get me up the hills near my house. On the other hand, I didn't want to overspend and get way more bike than I needed because I really just wanted to use it for my short commute to work each day and have it be a pleasant experience. I can unequivocally say that this kit (so far) has exceeded my expectations in every way! Terry has been very helpful which has also added to the to pleasantness of the experience. Kudos to him for offering a great kit at a great price!

I keep meaning to ask Terry about the blinky. I assumed the steady blink is a code for all ok. If it starts blinking different, I assume it would tell you something about what is wrong with it, like maybe low voltage or something. With the lifepo4, you will cut out before then. I've been really happy with the controller so far, I like the metal case for it's heat sink capabilities. You have it mounted in a good location for cooling. The only issue could be water from the wheel hitting it. On my bikes I take a piece of foam anti fatique mat an make a fender out of a strip of it. It's a bit ghetto, but it works great, and can't snag your leg or anything. I just zip tie it to the frame and the rack, and it keeps the water out of the electronics. The fatique mat is recycled from the dumpster so it's eco too.
 
Nice review. The kit does seem to be one of the simplest and easy to install available and I too am thinking about trying one out, in part because of Dogman's experience with it. Your bike at 50 pounds is quite light by ebike standards; is that with the battery and the bag onboard? What did the bike weigh before the conversion?

A question about the Topeak bag; what model do you have and does it stay secure with the weight of the battery? Does it ever jump out of the tracks?

Found an install manual for the we kit and it explains lights on the controller- not sure if it like the contorller on my aotema. What do you think Dogman- Terry? http://www.myebike.net/myebike_manual.pdf
 
Yes, that is the total weight minus rider and anything I decide to take with me on the ride. I forget exactly how much it weighed before the conversion but I think it was about 25 lbs. which would make sense. 15lb wheel+10lb battery. The moly forks ended up being lighter than the aluminum suspension forks so that was a little bit of help there.

I'm pretty sure this is the bag I have. So many different models of the MTX it is hard to tell.

I haven't had it jump out of the track yet, but them again I only have 12 miles on it. It seems really secure though and the battery fits in there nicely. I may move to a frame mount at some point just to have more trunk space. The battery being mounted up high doesn't seem to affect the handling hardly at all.
 
That will do for instructions. I can't agree about where they put the controller. Don't expose to water, but mount where the wheel will hose it if you hit a puddle. :lol: Also the pix show a rear suspension with the rack. the rack is gonna break that way. If the rack didn't inhibit the movement of the suspension, you'd see that tire rubbing the controller.

As for the battery, 10 pounds is pretty hard to feel, anywhere you mount it. Those that report issues with a rear rack carry have 20 pound 48v 20 ah packs, and often a rear hub too. so that is 35 extra pounds all on one end of the bike.
 
Looks like Wilderness Energy is now selling the same motor and controller we have offered for some time now. Imitation is the best form of flattery , I guess. We will always endevour to be the leader in the industry and be the first to offer the latest technology.

I will check with the factory about the green LED, but it's most likely the same.

The Topeak bags are great, I use a similar one on our top-end dual motor bike, but a little narrower without the big side pockets. They slide on and off the rack and have a mechanism that clips it to the rack securely. At REI coop the rack is $20 and the bag is $60. Two 36V 10AH packs fit inside, sweet!

On the controller to battery wire, I decided to extend the pigtail with the "trailer hitch" connector from 10" to about 18" with a bullet connector to anderson adapter. Working on the manual this weekend.
 
Wanted to post a little grade info. The steepest part of my ride according to mapmyride.com is a .5 mile stretch that has 130' of elevation gain which they say is a 10% grade.

Before the kit this was a real struggle to get up in the lowest of gears pedaling like crazy to maintain 3-5 mph and when I did get to the top I would be sweaty and tired. With the kit I can do 15mph with light pedaling and arrive at the top relaxed and dry. :D
 
Check out map my ride .com for grades. Use a short distance for the most accurate measurment. 130' over half a mile is not that steep, but part of that half mile could be very steep. I thought I had a 10% grade, but found on the website that it's only about 6-7%.

When did you start selling this kit? I bought the WE kit last year and this particular version was available little before that (sensorless, same controller since its a new design, wheel). Unfortunately I killed my motor (due to carelessness, not quality) but it was a good kit.

Edit - last year means before last summer, which probably would make it early 2008 or late 2007 kit.
 
What was your top speed at 36v? I think most of the WE kits sold in the first half of 2008 were 19-20 mph speed at 36v. this one does 23-24 mph so I think something did change in late 2008. I suspect a winding count change. My best guess is the current aotema is comprable to a clyte 407, and the old one close to a clyte 408. The controller was changed in 2007?
 
Was that meant for me?

I didn't use 36v - just went with 48v lifepo4 (mr.lau) and I believe I was hitting around 24-28mph depending on the road surface/grade. Same battery will do 24-26mph on small Bafang with exact same setup but with more torque which is always nice.

Typically I would cruise at 20-22mph and put about 900 miles? before the mishap (didn't tighten the screw on a new bike). I still have the motor/controller but don't have the time to troubleshoot.

Forgot - WE kit came with manual explaining what those light mean (blinking green means good I remember). I threw mine out but someone else must have them here.
 
Actually this week I crossed about 120 miles since going electric. In the three previous summers I had put 71 miles on this bike. I am still loving this kit! I did have an issue with the charger which kept me from putting a few more miles on the bike, but most of the time I was without a charger it was raining here, so it didn't cost me much ride time in the end. The charger issue was experienced by me and another person here on the forum that bought this kit about the same time I did. The insulation cracked on the wires on the battery side of the charger causing a short (which was a little scary!)



I ended up having to send the charger back to Terry twice due to Terry misjudging the correct size of plug needed for the battery connector the first time. The plug was not making connection with the post is the battery plug and not charging. Terry was great about getting the job done and not making me wait any longer than I had to. I shipped the charger to him priority at my expense, and he returned it to me priority at his expense. Thank you for that Terry.

The only other thing in the first hundred miles is getting the battery connections sorted out. I am not an electrical guy, so andersons are not something I am familiar with. Needless to say, I didn't have the correct crimping tool when I first installed the kit. I considered getting a tool and some more connectors (because I fubared the two that Terry included with the kit) but I didn't really want to go through the hassle and expense of buying a tool I probably won't have much use for. I e-mailed Terry to see if he could send me out a couple more already crimped on a length of wire. He shipped it to me very promptly, and I added some bullet connectors onto the end of that wire and it has been golden ever since.

I am still just so impressed with this kit, especially at the price I was able to get it for! The battery has been great. Based on charging times, about the most I have drawn off the battery is 5ah, and that was on an 8.2 mile ride. Of course I was pedaling to assist, but that is my ride style. It's nice to know that I could potentially go on a 16 mile ride without having to charge.
 
I just noticed this post. The cells in our LiFePO4 packs are polymer (pouch). We have other packs using cylinders and also Lithium polymer (not FePO4).
The manual is online now. http://www.hightekbikes.com/support.html

But you don't ship batteries overseas, just the kits. Is that because of concerns of freighting damage, or insurance reasons? (LiFePO4 may be safer than LiCo but the rules are always behind the engineering.)
 
We stopped shipping battery packs out of the country due to long shipping delays and possibility of damage. If there is an issue with the pack requiring testing or repair, the customer is faced with more delays and shipping cost. We want to provide good service and have satisfied customers. To that end, Hightekbikes is in the process of setting up a dealer network around the world. We should have one in Germany soon and are actively looking for dealers in Canada, UK, Holland, and Denmark. If anyone in these countries is interested, please contact us at dealer@hightekbikes.com We will post info on the website soon. Thanks for your interest.
 
In case anyone is interested, I am keeping a detailed log of the amount of gas I am saving by riding the e-bike so I have some idea of how close I am to recouping my investment. My basic commute to work is 6 miles RT and that is the bulk of the miles I am putting on the bike. You can see the info here:

http://spreadsheets.google.com/ccc?key=pIUDrADv35aTbDLPFV7OuTw
 
I find gas costs to be about 25% of the total cost of driving. So don't forget to at least double the number for what you saved on gas. Fixed costs like insurance and tags are fixed costs, but stuff like repair bills that go up the more you drive have to be counted too. I did lots of calculations and came up with a cost of 15 bucks to drive, and 3 bucks to take the ebike to work. So every time I ride, I get 10 bucks for the extra hour of time it takes me. Just enough to make it worth it. I'll never break even myself, but I sure am building a nice stable of ebikes! An extra $150 a month is enough to keep buying stuff.

Depending on your jurisdiction and your insurance company, you can lower your insurance premium by using an e-bike. Talk to your insurance company and tell them how many fewer miles you are driving to and from work and other commuting. Often, they will lower your premiums if you are driving many fewer miles.
dogman said:

Didn't you already break even with your 36-volt, 20-amp hour Ping battery? Or is the reason you'll never break even is because you just keep building new e-bikes?
 
So many bikes, so many motors, some sold, some burnt. I'm not sure how to calculate it anymore. But on the ping, yeah, on just the battery I calculated breaking even at around 3000 miles, and I now have about 4500. Definitely the best thing I bought yet was the ping. It's likely I'm broken even on the whole setup that I commute on by now. I've saved perhaps $1500 and have perhaps $1300 in that bike. The other bikes, though, I'm relatively sure I have spent more that $200 :roll: .

But it has gone a lot further that just a cheap way to work for me now. More of a hobby which can cost as much as you want it to. Lots cheaper than flying a hot air balloon though! I ride to work about 3 days a week, on average, and try to keep my spending down to about what I save by riding the ebike, about $160 per month. The savings piles up for me since I ride a bit further than some, but I have cooked off stuff a bit more than some, riding so far.

I'm not sure how I'd prove to the insurance company that I'm actually driving less. Luckily I live in NM where some of you, like califonians, don't even want to know how cheap you can register and insure a car here! Seriously, right now we have 3 cars and a scooter licenced and insured for what one would cost in califa. So the fixed cost is not too big a deal. Wear and tear is. One small repair can cost thousands.

You are mostly on the honor system ... until you have an accident. Then if you said that you were only driving 4,000 miles a year and your odometer was at 40,000 last year and it is now at 52,000 ... well, now we have a problem, don't we?

Yes, please do keep us happily in the dark.

P.S. I've been futzing apace on the eZee 20" rear-wheel motor and 36-volt, 20 amp-hour Ping battery. I haven't had the time to sit down and do justice to the experience yet. Lots of starts and stops and changes of plans. Going out to get an Anderson connector for the battery and look for some sort of container for the battery and controller such as a tool box. (Someone suggested Pelican boxes but taking a gander at the prices on their web site quickly disabused me of any thoughts of going with them. Maybe if I had a US$4,000 telescope or professional quality steady-cam, sure, I'd spend that much but I'm sure I can get some kind of metal tool box and stuff some foam or what ever that spray stuff is to insulate the battery and controller). Quick thoughts: The eZee motor is very good quality and well thought out. The Ping battery is an ugly, hulking, fire-breathing beast (but, once tamed and securely stowed away, it should prove to be an invaluable beast). Both companies demonstrated professionalism. See, this is why I haven't started noting my experiences yet. We professors can pontificate far longer than most normal human beings can tolerate listening to us. (Well, at least I'm not as bad a Reid -- but then again, I'm not nearly as quick and witty.)
 
Hey everyone. Haven't been on here much lately as I've been too busy riding and working, but I did want to get on and do an update on this kit. Bottom line is the kit does what it is supposed to do when it is supposed to do it. What more can you ask for? After 612 miles I am still pleased as punch with this kit. There have been no issues to report since the issue with the charger that I reported in an earlier post. The kit is just rock solid. I have yet to drain the battery to LVC, but I still estimate my range to be about 16 miles. I am hoping at Christmas time to get a CA and have more data but for right now my little $20 cycle computer works just fine. The battery has been fantastic and whenever I talk to someone that knows anything about e-bikes they marvel at the fact that I was able to get a kit like this w/ a LiFePo battery for the price I got it for. I know at least one person here in town has bought one of these kits from Terry after riding mine. If you are looking for an e-bike kit for a daily commute and are on a budget, I seriously doubt you are going to find one as capable as this kit is for the same money. Heck many more expensive kits (some kits that are MUCH more expensive) are not as capable as this kit. I researched e-bikes for a year before buying this one. I can't think of another purchase I have ever made for this amount of money that didn't have at least a little buyer's remorse. With this kit I have felt absolutely no buyer's remorse. There are cheaper kits out there for sure, but I don't think they give the same level of performance and simplicity as this kit....not to mention that they will probably come equipped with SLA batteries.
