Hello my husband has a woosh scirocco it started to make a whining noise when he took it out a few weeks ago but when going out today it got really bad & he said he had a lot of drag on the bike he was pedalling & struggling to get the bike to go up a hill that he's been up loads of times. I was with him on my whisper with no problem at all. He said it seemed as if his motor wasn't working as it should. He turned the motor off but it still whined
Any suggestions before he rips it apart
Thanks
