please is this a practical task or should i not bother ,? how i can convert my Giant new century
The problem i have is that my bike is fitted with hub brakes nexus hub gears, so from what i understand i cannot fit hub motor, i was wondering something like the old TGA wiper motor powered which i have already anyway in speeding one up ? i suppose cyclone type may do trick any ideas guys thanks.

If it were me, then I'd look at swapping the front forks for a set that could take v-brakes, and fit a front hub motor kit. My kit of choice would be one with a rear rack mounting battery, like the one from Alien.

Yes, you are very limited for options. There doesn't look enough of a gap at the rear of the bottom bracket for a normal cyclone mounting, and either Cyclone position would mean losing the chaincase. The TDK would also mean losing the chaincase.

The Currie Electrodrive motor cannot be fitted to a hub gear or hub brake, so that's out.

Straylight's suggestion is best, though you could also choose a disc brake hub motor like the eZee kit with disc caliper mounting forks.

The other thing of note is to make sure the new forks have a 100mm gap between the dropouts to accomodate the motor, but this will specified by the kit manufacturer.

Giant conversion

thanks for advice would it be best spring forks rather than rigid ? the other thing would it be ok to use 26" wheel ? i know they are a wee bit smaller than 700c

You would need new forks for either rim or disc brake to gain the mountings for those, unless you had mountings brazed onto the existing forks by a suitable company experienced in this. Nothing wrong with keeping rigid forks if you are happy with them, less complicated and less trouble.

You can use a 26" wheel and forks to suit, it would slightly change the steering geometry but not too seriously, though staying with the 700c might be best on all counts including appearance.
