Hello guys, I am very happy to find this place, lots of knowledge and information. I am reading ebike forums for quite some time and this one is the best so I registered. Since march this year I am new to ebike world but I plan to learn. My English is not very good so sorry in advance for mistakes.
I need some decent but relatively cheap 52v kit 1000w or more, for food delivery job, hilly terrain. And sometimes I use it to commute 70 miles on flat road, or when I ride my road bike to be able to take my girlfriend with me on some long rides with hills and mountains which would be impossible for her without ebike. So range is much more important than speed.
My first ebike was stolen recently :/ it was 27.5" mtb with some cheap chinese advertised "1000w" rear direct drive hub, maybe it was even realistic 500w rated not sure, and some 26 amp controller don't know which brand, probably JN (bunch of wires with SM connectors in a bag) and S830 display. And 48v 29ah 1400wh battery, Samsung 32E cells. I don't have experience with anything else, but it was great for me, near silent, had a lot of range at my usual speed 10-15-20 mph and enough of torque for every hill. But I pedal and shift a lot, to extend the range and it's a habit, I was avid road cyclist and racer.
Now I would like something similar, or a little better and faster if possible without compromising efficiency and range at low and moderate speeds.
So, first and important question would be, is it true that 1500w motor eat more battery than 1000w at same speed 10-20 mph? I received conflicting info from ebike builders. I would love a little bit more top speed when I need it, but not If I get less range at my usual speed.
I bought new donor bike, 27.5" mtb, 135mm rear hub. Although big city, Belgrade has only a few people making battery packs and ebikes. As battery is most important I plan to buy biggest available here (downtube format, polly case) although expensive (800 eur). It is made of 98 cells LG M58T, 52v 40.5 Ah 2100 that's how he advertise it. Realistically it's probably a little less than that? Use JBD bluetooth BMS. And he offers them with 30 40 and even 50 amp BMS continuous. But he said to me that 30 amp controller is maximum that is safe for some MXUS 1000w DD motor he sells. Is it true? It is well enough for me, but I was thinking it would be nice to have a little more power when it's needed (rarely and for a short time) if the battery is already capable for more.
I would like to save some money (and learn), buy kit on aliexpress and install it myself if it is possible and easy enough. No pas, throttle only. Can somebody recommend me some decent kit or motor/wheel and controller, display separately? I have a lot of experience with bike mechanic and maintaince, I have all the tools and know how to build wheels (although I prefer to buy complete wheel and avoid hassle with spoke length). But I have no experience with ebikes, so many different connectors, controllers, displays and protocols. I cannot buy Grin RH212 or Leafbike stuff, I need it delivered to Germany.
I know I would like controller with waterproof connectors, with support for headlight/horn like I had. And some newer color display, if they now have more (useful) features than my old S830. And I would love cassette freehub, to be able to use 11 or 12t cogs and pedal at top speed, extending range and relieve strain and heat off battery/controller. But I am told chinese freehubs don't last in rain, and when they need to be replaced you need to open whole motor. So if that's true then I would need to stick with 13-28 threaded freewheel.
Here are just some examples I was looking, but I am baffled, as I read more it gets worse... Even if I read for a month now, it's impossible to figure it all out on my own witbout asking for advice. I am scared to order something and to find a mistake later, that it does not fit or I cannot install it. So many little details...
