Byocycles City Speed 20" Folding Electric Bike


The UK-based company, Byocyles, present The Byocycles City Speed 20" Folding Electric Bike. The practical e-bike with flair. Simple to fold and transport and at an amazing price for a bike of this power and build quality. This compact but fully featured ebike is great for cycling around town or rural areas. It has a small profile when folded so you can pack it into a car or on a train.


The City Speed is based around an 17-inch folding alloy frame with the fully detachable lithium battery fitted behind the seat post. The 3 points folding frame is light enough to be carried when the need arises. The 7.8Ah battery has a range of approximately 18-25 miles. The 10Ah battery has a range of approximately 28-35 miles whilst the 13Ah battery will take you to approximately 43-50 miles. With a charging time of 4-5 hours from flat, you can easily charge at work during the day. 


Controls are dealt with via a LED display panel with three levels of assistance along with a battery strength gauge and a light on/off function. This, in tandem with the 6 speed Shimano gearing, means you can benefit from graduating the power to suit any given gradient of the terrain. The brushless 36v - 250-watt motor is mounted within the rear wheel. Within one cadence of the pedals, the motor kicks in and will remain so, up to 15.5mph (UK Restricted Law). Just by applying the brakes or by ceasing the pedal power, the motor cuts out, allowing you full control of this nimble folder.


Attention to detail is what is on the cards for the City Speed, everything from the folding levers to the wheelset with double-walled rims and stainless steel 14g spokes has been carefully chosen to be strong and long-lasting, but also light. This is reflected on the scales as it weighs in at an impressive 20kg (including battery).


Gear componentry is looked after with Shimano, (TZ40 derailer and TX30-6R gear lever) along with a KMC branded chain.


20" Double Walled Alloy Henli rims are fitted with Duro Urban 20 x 1.75 tires which are stopped with Winzip V-Style brakes.


Fully featured, an industry-standard 36v 7.8Ah/10Ah/13Ah range package, practical and at a great price. The Byocycle City Speed is a worthy consideration.

How will my electric bike be delivered to me?

We supply all-electric bikes fully assembled and built to order. They will arrive boxed and once removed from this transit box only the simple attachment of the pedals and the straightening of the handlebar will be required. Please carefully unpack your bike and keep the packaging and box in case you should need to return the bike.

For electric bike orders, we will always email our customers with the expected date of despatch to ensure that the date of delivery will be suitable before despatch.

For orders with a value over £20, a signature will be required upon delivery; we cannot instruct our couriers to leave an item in a safe place or without a signature.


How will I know when to expect my item(s)?

Your email address is recorded during the ordering process and we will inform you when your item(s) are dispatched (Please note the above detail regarding built-to-order / assembled items). After we have dispatched you can expect delivery of your item within 1-2days (UK Mainland) and 2-3 Days (all other UK areas) although these time frames may be affected due to courier volumes during this time (COVID-19).

If your order is for an electric bike you will be informed of the delivery day well in advance. We will also let you know as soon as possible if a delay in the delivery of your item(s) is anticipated.


Please note:

° Remote UK postcodes and addresses in the British Isles may take longer than one day to have their orders delivered. Therefore, orders that we send on a Next-Day Shipment may take up to three days in these areas.


Eire & European Delivery

From Jan 1st, 2021 we will be adjusting to the Brexit post-transition situation and as a temporary measure will be suspending delivery to these areas.

Please note, any delivery issues must be reposted within 14 days.



What should I do if I need to return an unwanted item to you?

We feel that you should be totally satisfied with your purchase. If, however, you wish to return an item as unwanted then you can return it to us within 14 days of purchase.

When can I return an item?
