How does it work?
- Purchase any BYK at Glow Worm
- When your child is ready for a bigger bike, trade it in for a discount on the next size up
- Discount is based on original purchase price
- Trade-in is subject to workshop approval*, bike must be in good used condition
- Only one trade-in per new bike
Use the table below to work out your discount:
| BYK Model | RRP | Maximum* trade-in discount |
|---|---|---|
| E-250 | $369 | $74 |
| E-350 | $409 | $82 |
| $469 | $94 | |
| E-450x3i | $599 | $120 |
| E-540 | $499 | $100 |
* If the bike is in poor condition, discount may be less than the maximum OR trade-in may not be approved by workshop
