Whilst it is shocking that the rules seem to be biased in favour of car owners over bike owners car manufacturers generally keep very quiet about issues requiring recall until such time as recall arrangements are in place. They don't offer full refunds because a car needs a recall. Car v bike is not a good comparison. The OPs contract is with whichever retailer sold the bike, surely, not with the manufacturer. And consequential losses, inconvenience and emotional distress won't be covered.
