Hello

I want to try to ditch my car for my bike, the road to work is 14 km, I want to travel that far in around 20 min. I will be using my current bike and rebuild it. I would want to try to make it a 365 days a year commuter here in sweden, so winter tires is a must and also a kit that can handle snow and ice.

Desired max speed on level ground. mph or kph
45-50 km/h
Desired max range at what cruising speed. mph or kph
50 km
Preferred bike wheel size, or wheel size of bike you want to convert. Most common kits are for 26" wheels.
I will convert my current Scott sub 40 from 2011, 700c, or 28 inch.
Brake type of motor wheel. Disc or not.
V-brakes to start with, will change to disc if needed.
Rider weight.
80 kg
Terrain. Exp: mostly flat, some short hills under 20% grade, I want to climb mountains, etc., etc.
Road to work is mostly flat, there are other ares where there is a steep climb, 20% for around 700 meters.
Budget.
around 1000 EUR for motor, controller, parts and battery.

So far I was interessted in a bbs02 or bbshd setup, but I have read through the wiki and other posts and it is clear to me that that it will require more service than a rearhub. I would also like to have a cycle anlyst hooked up with a better PAS then the bbs has. I know you cna hack the bbs and connect a CA, but I dont really want to start with those mods with my first build.

I think my ideal setup would be mxus 1000w, with a grin controller, pas and CA. Problem is I cant find a mxus in europe, my 2nd choice is a crystalyte HS3540, but that seems a bit over the top for me? But on hte other hand I can get that in europe, even thou the crystalyte shop seems to charge a good premium...

To summarize I seem to be found of a rear hub around 1kw, with a grin controller and CA to go with it. Any suggestions with possible setups and suppliers or am I doing this completly wrong and should rethink this?

Thank you for all your help and all this knowledge that is on this forum.
 
Welcome, it sounds on key to me and that's a quality build. You're obviously aware of cheap kits and want better quality and service, yes?
1000 watt rear hub is great for commuting those speeds, and much better than middrive for it imo. Get a reliable quality pack for sure! (15ah might do one way with no pedaling.) I know Grin sells from Canada, but but don't know of EU. If canada is no good http://www.ebikes.ca maybe http://www.em3ev.com has the stuff too I think.
 
Ebikes.ca could be the way to go, but they only have the ezee hub in 700c, not the crystalyte, dont know why since I can get it in 700c in europe...

It seems like the price is the same for both the crystalye and ezee, but i get more motor with the crystalyte, or maybe I'm wrong? It seems like if I would later on want to get a better frame and more power I have the possibility with the crystalye but not with ezee, but once again it is hard to find any recent review on either ezee or crystalyte...

Well yeah, I can do that, can do that on aliexpress aswell, the question is, what am I buying? I will be using this for work, I rather pay an extra 100 eur and make sure I get to work instead of losing that money they day my bike is broken and I cant get to work or I'm stuck halfway...

What are they good quality kits/motors availble in europe?
 
Welcome to the forum!

What you want is in the realm of possible, with one problem. 20% grades aren't something most hub motors can do very long. The HS3840 can't do it at all on a 20A controller, can do it on a 40A controller, but will melt down in just 4.2 minutes. The MXUS will do much worse. This simulator can help you see the problem: http://www.ebikes.ca/tools/simulator.html

The answer is to use some form of through the chain drive. The BBSHD should be able to handle it, geared low enough. Being a unit with all internal gearing, it will be more reliable and all weather ride-able than some of the more powerful kits.

700C and all weather may not go together well. You're going to have a whole lot more power available, and 700C tires aren't going to be able to keep up . If your frame allows 29" tires to be fit, then that's the way to go. Otherwise, you may want to consider running a large tire on a 26" wheel. For example, a 700C x 32C tire has the exact same diameter as a 26" x 2.5" (2155mm), But the 26" tire will have a much larger contact patch with the road and get better traction.
 
Checked the hill with digital maps and some googlig and found out I was higly wrong, you climg 45 m in 1km, so an incline of 4,5%. I feel kinda dumb now...

But never the less, it's good to learn from your misstakes. Is it so that my presumptions on the bbs are wrong? As far as I can see from the different videos and es wiki on midhubs there is more service on the bbs system compared to a rearhub? Any opinions on eZee vs crystalyte or this chinese no name brands that are all over the place?

I will check out the 26 inch alternative, thank you.
 
I've had a full Crystlyte 48v30A kit with HS3540 in 700c with a 38c Schwalbe. 50kph was fine, but honestly the contact patch/rubber stiction wasn't enough for wet weather. Also, your saddle needs to be Plush! Really Plush. 700c rigid at 45-50kph wasn't comfortable.

As you've said Direct Drive is mostly trouble free. HS3540 is quite waterproof too. Drunkskunk has hit the nail on the head with looking at 26" with fat tyres. Crystlyte kit is semi watertight, condensation in the screen can appear. MXUS link in Europe. 48v30A battery range at 50kph is around 50km, LiFeP04 it would start flagging after 45km up 3.5% incline.

Leafmotor 1500W has been batted around as a cheaper alternative, it'll give you plenty of spare cash for a decent battery pack.

Or just get a leaf hub @ 199 Eur an 'old' 3Kw Adaptto Mini-E @ 365Eur with BMS @ 90Eur and a 30A coil @ 42Eur = 696Eur ex del with 300Eur for the 12S LiPo (wait 5 mins and the price drops to 94 Eur per unit) or if your handy or know a guy who knows a guy get 90 INR 30E at 3.3Eur and make a 15S6P pack which at 45kph will hit your 50km range.

All the motors come from China. It doesn't matter where you buy it. I've got 24K+ Km on my 1000W motor I bought 5 years ago. It was the cheapest option then. I wouldn't touch a Crystalyte motor. From what I've read here over the last 5 years, their quality is no better than most and worse than a lot. Try and find a seller in your country if possible. I know there has to be at least one. If you'd fill in your location that shows you're from Sweden, maybe some of the Swedish people here can point you to one. Or don't and they will never know where you're from unless they read a post where you mention that. I've given you my advice. Do with it what you want.

So, I have a seller for adaptto here in sweden, already spoke with him about a different build. The funny thing is that the adaptto controller will be as much as a CAv3 and grin controller... PAS seems to work with the adaptto too. I will prolly get the battery from him too so that it will be integrated with the adaptto bms.

As far as I can tell in this thread, there is no clear difference between the different makers of hubmotors? People are saying crystale are good, others are saying they not worth their price... Leafhubs seems to be equal quality but cheaper... To be honest, I'm not much wiser when it comes to the hub motor then before. I'll look into more reviews and threads here to see where to go to...

When it comes to the great advice for tire I found this, http://www.bikeinreview.com/2013/01/continental-travel-contact-reflex-tire-review/, I will try them out and see where it goes, if not happy I'll respoke it to 26 inch or similar when I'll change my frame in the future.

The questions is how well the adaptto will handle a 1kw motor just doing 500w or similar...

Will do the battery holder myself, will try to make a build thread here.

Thank you all for your input.
 
Take a look at my calculator-You'll know exactly what you need. 20kb, it's free and the imgur link has a screenshot. You'll need java tho

Hi

Just a quick update on this, managed to get a falco 500 hx system for less than 400 EUR, from fasterbikes.eu, that was cheaper then just getting a leafmotor or crystalite. Got the controller and all the extras with it aswell. So will try it out, I have read through the falco thread and I look forward to test this over commercialised motor and see how it goes. Alex from this forum is making the battery for me and most of the parts should arrive next week.

Total cost so far have been around 950 EUR, that is motor/controller/hmi/freewheel/tourque arms, battery, wheelparts and build cost. I hope I can start to build it soon, was planning to make a small build thread.

Thank you all for helping me out.
 
Nice, more ebikers from Sweden.
I am running an adaptto + leafmotor setup on my "summerbike".
Very reliable. Wintertime I am using an upright tilting trike to have a safer time on slippery surfaces.

If I would ride a regular bike wintertime, I would make sure to have 26" wheels to have access to the best spiketyres.
This is from my Sundsvall perspective, I bet Gothenburg means alot shorter winters and less ice/snow.
