A budget option worth considering
I was looking for a folding E-bike to use mainly for leisure and to take on public transport. I have a regular road bike which I use for short rides day-to-day. Overall, the Z20 Pro meets my needs at a good price. The bike arrived in less than three days, but it took some time to get it set up. There is not much assembly required, but there was very little by way of instructions, either in the manual or online. Things that should have been quite simple took a lot longer than they should have. In particular, the screw for the front light and mudguard was very difficult to get undone. I eventually did it using a pair of pliers to hold the nut steady. I don't know how I could have done it with the tools provided. I raised this with customer service but they just directed me to their Youtube channel, which didn't answer my questions. Also, the saddle was loose and I couldn't tighten it with the tools provided. I took it to a bike shop, and they fixed that and fine tuned the rest of the bike. I would recommend anyone to get their bike checked over after assembly to ensure it's roadworthy and performs to the highest standard. The other issue I had was with the battery which I found wasn't locking in and kept falling out. I raised this with customer service and they replied quickly with a video of the battery lock in operation but have yet to respond to my follow up email. Repeated attempts to insert and lock the battery led to the pins getting bent so the battery no longer fit. I had to make an emergency bike shop visit to get it fixed. I have now worked out that you need to lift the battery slightly for the lock to engage - not a great design. You can't expect the best E-bike for under £700 and when it's up and running it meets my needs and expectations. But the lack of clear and comprehensive instructions is concerning. It could be very dangerous for someone to ride one of these bikes which hasn't been assembled properly. If you are looking for a low budget bike this is worth considering, but if you need something reliable for daily use I would go for a higher price range.
