Bike sizing by Ivor Biggin

I see more people out on new ebikes than ever. What I notice most about them is not the use of Hi-Vis clothing, although this is certainly eye catching, but the fact the bikes are sized wrong for the rider. Ebikes are sized the same as non ebikes, in that they are measured from the middle of the bottom bracket axle to the top of the seat tube ( where the seat post clamp fits ). If you're standing astride a mountain bike there should be three inches of clearence between you and the top tube ( for maneuverability).On road bikes this should be  one inch. Hybrids between two and three inches.

A frame that is too small means that the seatpost is often extended past the maximum safe use height. Additionally for comfort, the handlebars have to be raised to match, making them higher than is safe. The riders leg isn't extended enough and over a few miles this can cause cramping of the thigh muscles. Bikes that are too large mean reaching the handlebars comfortably isn't possible and the bike is difficult to handle. This can also mean over extending the leg and causing knee problems. 

Regardless of bike type, to get the right saddle height; with your foot at the bottom of the pedal stroke, you should have a slight bend in the leg ( about 80-90 percent of full extension).

Client Testimonials

Hi Raj.
I just wanted to thank you for your kindness and help.
My dad who is 72 bought himself and his wife a kit each a couple of years back and he says it is the best thing he has ever done.  He stops and tells anyone who will listen that buying the bike has changed his life. He already had a bike but found it such a struggle to do anything other than ride around the streets so he didn’t really bother. He heard about electric bikes and went on a mission to find the best. He settled on Cyclotricity.  He started off cycling a short distance and then using his throttle to keep him going whilst he had a little rest.  Soon his fitness improved and now he goes out for miles and uses the throttle less but loves having the freedom to take on long distances. 
Best wishes
Dear Ben
I would just like to Thank you for the fantastic service that I received from your company. As you know I had an issue with my digital meter, I had a phone call from Ben at Cyclotricity the same day and this morning a new replacement had arrived.
This is fantastic service, I am so pleased that I purchased my bike through Cyclotricity. I will log onto your website and write a customer review and I am thinking in the summertime I may even purchase a electric bike for my wife, if and when I do I will certainly buy it through Cyclotricity.
Keep up the good work, I wish you all the success in 2017.
Normally people write in to complain but I feel that it's nice to tell people that they are doing things right.
Kind Regards

Hi Raj,
I just want to thank you for all your support through this build. You were/ are a great help!! Thanks for getting the technical team involved where necessary!
I feel like I should hire a model to stand next to the bike, to be able to send you a very nice photo!! As it is I will be wise and you will appreciate it if the photo is only of the bike and doesn't have me anywhere near!!
Have a good day!
