Lovely bike with best service

by from Bristol on

Bought from Bristol 50 cycles month ago. Michael and Anthony really helpful with smile in their face. After 3 hours in the shop finally decided to buy it and I'm very happy to made that decision. The bike is lovely and so smooth riding. All my colleagues surprising how fast I climbing up the hilly way to work and leave them behind. No more sweating with a happy face when arrive at work faster than usual. Very reliable and she is mine :) Thanks for the great service to the guys by 50 cycles Bristol!

The best investment I have made!

Five Stars: Bought my first electric bike through the Cyclescheme with 50 Cycles. The best investment I have made! I just love my new electric bike. 50 Cycles were really helpful with expert knowledge and offered excellent customer service and support. They have a good range of well-reviewed bikes and are well-informed about the Cyclescheme. I also get a free service after a month of cycling to make sure the bike it ticking over OK. Can really recommend 50 Cycles for all your electric bike needs – go and try one out and save Bristol from its awful traffic issues. Hills are a breeze!

What more do you need!

by from Whitley Bay on

Owned since April 2015. Expected excellent German build quality. Very discrete - few folk realise it's an electric bike, which I like. The 3 levels of assistance give me enough flexibility to cover all my riding situations. I've not found out the absolute range but for me at 15 stone I think it's probably about 30 miles in real world conditions. it's all the electric bike which I need at an affordable price. Very happy owner!

Excellent Bike

by from Lancaster UK on

I am in my late 60's and wished to take up cycling again. The groove 7 fits the bill incredibly well. It is an excellent bike and maintains the German reputation for reputation for high quality build. The power assistance levels are just right and it enables me to climb all the steep,hills of our city without being too much out of breath! the service from 50 cycles was also first rate and I can highly recommend them.

I absolutely loved this bike from my first trial ride - it had just arrived in the store! Its systems feel totally intuitive to me (it it just because I'm German too?), it is extremely well balanced and the gears are wonderful. I love its particular trick of giving immediate strong assistance when starting up from standing on a slight hill...and the push assist, on steeper hills. Because yes, you will appreciate that, because its one weakness is, as with my previous bike, conquering the really steep hills which it slumps on after a short while

I look forward to every single journey with it, come rain or shine, and even in darkness as the built-in lighting system is brilliant and actually lights up the road for you! I am so happy with this and am confident it will do me for a good many years!
