After my recent heart attack apart from feeling down in the mouth about my future health i was sad at possibly having to hang up my cycle clips for maybe an indefinite period. I considered buying a petrol scooter so as to be able to still enjoy riding around the country lanes where I live in North Norfolk. I still might invest in one at some future date but at present I`m on the normal 4 week driving ban but thank God I can at least still ride my Electric bike.
Riding along the flat and downhill shouldn`t be a problem on the bike but pushing uphill at this early stage in the aftermath is surely going to be a problem that will confine me to very few local routes.
Then I got thinking! I`ll just ride on throttle on the uphill sections and duly set off for my first ride since being released from hospital. OK, I got round the course but the uphill throttle only sections were a bit disappointing and speeds at times dropped to wobble levels.
Then I had a new thought! what if I stripped down my Evans/Alien conversion and fitted the front drive hub to my powertrek plus the controller and battery? how would all the weight on the powertrek affect the performance? Well, nothing ventured , nothing gained and with the fitting of the extra throttle to the left hand side of the bars all was ready for a road test.
Wow!!! what a hill climber with both throttles full open. Anyway, having done a number of miles I can pedal using the pedelec of the Powertrek backed up by the throttle of the Alien hub when needed and I`m pleased to say that it has put me right back on the road again with the added bonus that if I become tired in these early days I can ride home with a choice of one or two throttles. In fact, the performance with those two 36V 250W motors is so good that I find myself wizzing around certain parts of my routes with my head down and both throttles fully open with a big smile on my face.
Now my big decision is whether or not to leave the Powertrek as is and buy another kit for the Evans?

I`m also very pleased about the general look of the bike, it really doesn`t stick out as anything much other than a normal single motor e bike. I`ve fitted crampbusters to both throttles and positoned them within reach of my bar ends and getting used to lifting one and pushing one away to get the power from both throttles all at once is as easy as falling off a bike:-) no pun intended.

Thanks for reading
