@Blackgold: Yes, it’s the same model. I bought it from Decathlon in May 2025. I’m not sure how to check the exact mileage, but I’d estimate around 600–800 km from commuting during summer.

I could do €550

Is this the same model available from Decathlon for €950 brand new? My rule of thumb is 50% for second hand electronics would you accept €475? How old is the bike and how many KM is on it?

@Daithi.walsh: The assisted speed is up to 25 km/h, which is the standard legal limit for e-bikes in the EU

€550 works for me.

@rimpala: Hi πŸ™‚ I mainly used it for commuting during summer. My daily trip was about 4.5 km uphill to work (mostly using Boost mode), then 4.5 km downhill back home where I barely needed assistance. I usually charged the battery every 3–4 days and never had any issues with it. I also never fully drained the battery to 0% β€” always kept some charge left.

I could lower the price to €600, considering all the extras included.
