Thanks, by Googling for Aikema I found an extremely similar bike, I'd say it's the same one under a different brand name. That one says: battery: PORTAPOWER capacity 8,7Ah / 313.2 Wh motor: AIKEMA Front hub motor, 36V, 250W mode switch: TGK-36-WM LCD: King-Meter LCD By Googling PortaPower, I found probably the battery used in this bike: it's either YL-TBH1 or YL-TFH1 or YL-TFH2 with supposedly Panasonic cells.

An new model people recommended me from Neuzer has a frame battery and a Sturmey-Archer 3-Speed Hub. As I read Sturmey-Archer 3-Speed Hubs are generally considered very reliable, even more than Nexus 8, so that's a good sign, but how concerned I should be about frame batteries? This is an other super-low price model (710 EUR), hopefully the electronic system is simple, but I have no idea. Specs say motor is: KKM100SX, does this mean anything at all? This is how it looks: Or is the MXUS model with generic battery a much more future-proof buy?

Do you mean that this proprietary looking battery can be replaced with a generic one in the future?

Thanks for the good points, I'm definitely not considering second hand pedelecs any more, since the ones I was looking at were the same price as new low-end ones, say 800 EUR. I'm now leaning towards buying a low-end one and just swapping the too-cheap parts immediately, like V-breaks and probably rims in the first few months. My question is which one of the following you'd buy (both cost around 800 EUR): - Decathlon Elops 120E: 36V/313 Wh rear-hub unspecified motor/battery/controller, 2 years warranty, original battery: 300 GBP - Neuzer (my local brand): MXUS XF06 front-hub motor, MXUS LED890, MXUS 36V, 11AH battery, 1 year warranty. I think the bikes are quite similar, my question is about which will have better support later on? Is the MXUS system reliable and easy to find replacement parts later on or can it take generic batteries, etc? Does anyone have experience with the low-end Decathlon bikes here?

Yes, a step-through frame, like the bikes popular in the Neatherlands is what she'd prefer. I've been reading and it seems to me that the most reliable / easy to maintain solution for her would be one with a hub motor. So maybe I should buy a cheaper new bike and just replace the very cheap non-electronic parts, like breaks and maybe rear derailleur.

Hi, I'm looking to buy our fist e-bike / pedelec, I'm looking for a model which my 60 year old mother could use to commute to work (2x6 km, 60 meter elevation). She doesn't want to spend too much money on it I'm looking for something up to 900-1000 EUR. My question is whether I should look for second hand "lightly used" bikes with higher specs or base/budget model brand new ones. For example I could buy a cca. 2015 Kalkhoff bike with Panasonic 26V mid engine system and Nexus 8 speed hub which only had under 1000 km / 8 charges in total. Alternatively I could buy a new bike from a local brand (made in my country), with very basic specs, or something from Decathlon for the same money. Front hub MXUS XF06 engine, Shimano Tourney TZ50 rear derailleur, battery on the rack, so everything super basic. I don't like any of these specs, but since its a local brand there'll probably be replacements for a long time and probably loads of local knowledge in the coming years. Basically for non-electric bikes, I always bought second hand as fixing bikes with new parts was always easy, but with e-bikes I'm worried as I have no idea what'll happen if something breaks in the electric system. On the other hand I heard that Panasonic systems are very reliable. Which way would you recommend me?
