Lovely little bike

Having had 10 days to get used to the BK6 I still rate it a good buy. I would like a cruise control facility as on a flat road, even in top gear, you have to pedal really fast to have any effect at all - maybe a higher gear would also help.
The tires were quite a low pressure when I unpacked the bike. I pumped them up to 35psi - the tyre actually specifies 40psi but 35 seems fine.
I will need to play around with the handlebar positioning as, at the moment, my arms get quite tired after 40 minutes or so.
The bike is quite heavy so I'm glad I don't have to carry it up steps. The saddle is comfortable and I am glad there is a low speed throttle that helps to get started, especially uphill.
I feel a bit mean only giving 4 stars but for the price it is really good value. I'm sure there are better bikes but at a significantly higher price.

I chose the RK6 as it is very competitively priced and seemed to meet most of my needs. The battery and range were better than many others and I wanted a step-through design. I ordered it on Sunday and it was delivered on Wednesday morning, well packed. It was quite hard to get the bike out of the box but then it didn't take long to attach the pedals and unfold the bike.
It looks well made and was considered "cool" by ny 15 year old granddaughter!
I have never ridden an ebike before so it took a bit of practice on our quiet road. I discovered that it does have a throttle which is not mentioned in the advert. This only works at low speed but is useful in getting started uphill as the motor only kicks in after a full revolution of the pedals. I'm thinking that I should maybe have got a bike with a torque sensor which responds much faster. However, I think I will get used to it.
Other reviews say that it is good on hills but they must have less steep hills than here. Coming up the steepest local road it needed plenty of pedal assistance in the lowest gear to keep the bike moving. On the website they claim it can climb 25 degree hills but I would dispute this - half that would be more realistic.
I also really wanted hydraulic brakes but the manual ones on the BK6 are not bad. On a flat-ish road it is quite easy to maintain 15mph on level 3 assist. Level 2 helps only up to 11 or 12 mph.
The lights seem to adequate and the rear light also gets brighter when the brakes are applied. Walk mode works well and at a good walking speed. I was nearly put off buying it due to the "Rock Our World" slogan on the side. I might just cover it with black adhesive tape.
Overall, I'm pleased with the BK6 and I'm sure I will be more competent on it with a bit more practice. I will do another review when I've had more time on the bike.

This is an amazing bike. Value for money. Very sturdy. Easy to use. Quick. Goes up hills which was a winner for me, as where I live is quite hilly. I’m not a bike rider and I’m 64 years old but I would recommend, I really enjoyed riding this bike. When delivered it was missing the air pump but I contacted customer services on their chat app and it was sent and received within days. If only all companies were like this one!

I bought this RCB RK6 bike because it is very different from the usual bikes on the market. It is a portable folding model with a cool appearance and is available in black, white and pink.

The bike arrived in less than 5 days and was very well packaged. The assembly process is very simple and intuitive.

The front and rear lights and the seat are very beautiful and well made.

I rode the first ten kilometers to get a feel for the bike and the battery assistance was perfect. The hills near my house are very steep and it keeps the speed steady.
