having received my item(only two days after ordering)i set about putting it on my bike. i was delighted how well made this is, being so strong and very sturdy, and i found it so easy to put on my bike. i have a folding 20" electric bike with the battery compartment housed in the seatpost frame, and this carrier sits easily above it, and this in turn dosen`t cause a problem in getting to the battery. anyone who is thinking of getting a carrier for a folding bike, then i would say that this is an ideal solution, due to the ease of installing it(took me about 10 mins from start to finish), and as i say, the quality of this product(strong fixings as well). it easily accomodates a double pannier bag as well. hats off to the manufacturer for producing such a well-priced, first class, gold-star item, and i would certainly recommend this product.
