Customer Reviews

Based on 6 reviews

I bought the Legend Siena 24" folding electric bike so that I could take it away with me in my campervan. I wanted a folding bike that resembled a full-sized bike as closely as possible. I was delighted with the bike. It is nice looking, easy to ride and fold. It is fast and responsive when assistance is needed. I am very happy that I have chosen the right bike for me.

David T
Brilliant service and value for money

Excellent service from Eco Bike Co from order to delivery.
Bikes delivered direct from Europe with EU plugs. Eco Bike supplied UK adaptors next day FOC so we were up and running without delay.
We needed folding electric bikes to fit in the boot of my car and I didn't want 20" wheels. The Legend SIENA are perfect, fold small enough and not too heavy at 21kg.
They are well built and ride well with a good range on the battery. Been out every day since delivery. Mahle Ebikemotion phone app connects with our android phones without any issues and records trips and gives various data. Overall we are very pleased with our purchase. Love them.

Jenn Rem
love it

I absolutely love the bike, it's very handy for a hilly city like Glasgow. Great that I can take it in and out of the office with me too.

Stephen Moore
Top quality folding electric bike

Very nice well thought out design, good components and nice quality feel to this bike from Legend. Great blend of folding convenience and practicality - not intended to replace a full size bike, but a very good bike.

Tilly c
Love it!

I wanted a full size, folding bike. The Sienna fits the bill perfectly. Easy to use and fold/ unfold. Whizzes up the steepest of hills.
Only drawback is the weight. Quite heavy for lifting in and out of car boot.
Very quick delivery and packaged very well by Eco bikes.
Love my new bike.

Susan Pennington
Legend Bike

We had to wait awhile for our bikes to arrive but when they did we were delighted with them.
Eco Bikes kept us informed of the delay and were great. Recommend buying any bike via them.
