I don't think that you can buy a Specialized or an Haibike with carbon frame for less than 5000 euro, but Specialized is Specialized as someone can say.
And I'm the frist to like their products, but here we want to give you a new concept of electric bike, the possibilty to use training mode with cardio sensor that will adapte the Motor Power in function of the cyclist Heart Rate.
We really like to get your help in case you like this product support us or just share with your friend, as I'm an e-biker like you I'm sure you will like it.

please feel free to add me as Facebook friend

I like the look of that and to produce a geared ebike at the weight is a good effort. Along with the heart rate monitor link I think you could be onto a winner . It will appeal to trendy executive types who have a bit of cash though , not the old fogies ( edit.. I include myself in this category in case anyone feels I am being insulting ) or the young airhead that haunt this site I feel.
good luck with it.
regards

no just pointing out carbon frames are not that much these days and a motor and batt could be added for not much more to convert it diy.

I totally agree but the additional cost of this bike is due no doubt to its unique selling point - the heart rate feature.

Makes me ponder if a raspberry pi(or other sbc) connected between the battery and motor on a normal e-bike could do something similar.mmmm

If I had a smart phone, the heart rate monitor would scare me to death.
Why not add a blood pressure monitor?

this will be second step, we are thinking also to add a special training program already on this first model that will help you get fit faster without to much effort and later to use this kind of system to meke effort test outside of cardiology cabinet

Are you using an optical HRM on the wrist band? How do you find its performance?

The reason that I ask is because I use a Garmin Forerunner with an optical HRM when running and occasionally when cycling. I find that it outputs HR with reasonable accuracy, but is slow to react to HR changes due to work effort. For example, if I'm doing 400 meter track sessions with rest intervals, the optical HRM is very slow to react to falling HR during rest periods. It's also slow, but not as bad, to react to rising HR upon resumption of exercise. When I use it for cycling the above is even worse.

From what I read, this seems to be a shortcoming with all wrist band HRMs and in particular optical sensors. A chest band still seems to perform the best.

I'm sure that I remember Kalkhoff producing a bike which did exactly this about 3 years ago, varied assistance based on HR fed to the bike via a chest band. I don't know if they still make it, but someon off this forum bought one.

Just wondered why you chose a carbon frame? With 6061-T6 ally and good design an ally frame is not much heavier and carbon does have attachment problems with heavy parts.
Also why does it need to be a Kickstarter project,you could build 50 of those bikes for an investment of maximum £50k.
Every time I go to Eurobike I see a few Kickstarter projects but I have never seen one go beyond the prototype stage,perhaps others can tell me if I am wrong? Developing and building e-bikes is not expensive,the most expensive aspect is marketing .
Good luck,but I think you are going to have to use your own money to get this project rolling.

The wristband has optical sensor for HRM like garmin, and for sure the chest band has better performance.
With this bike you will get fitness band but you will be free to use any bluetooth chestband in case you need more accurancy.

I chose carbon to save weight and to have a better design and harmony of this Urban e-bike. Rear hub is not connected directly with carbon frame but we have special aluminium insert to make the structure more solid.

I agree with you that's why i need your support, otherwise i wouldn't need kickstarter and i think that with £50k you can't make a good marketing strategy

I think carbon frames give a more pleasant ride than aluminium. I find that aluminium frames are too rigid and transmit every bump in the road into the rider via seat and handlebars. Carbon on the other hand is more forgiving. It reminds me of riding the older steel framed bikes in terms of comfort.
