What do you need help with?
Where's my order?
Kits and batteries ship within 7 days of ordering. Standard delivery takes about 6 weeks, express 2–3 weeks.
- Your tracking number is emailed as soon as it ships.
- Batteries and kits often travel separately, so one may turn up first.
- Past 6 weeks with no movement on tracking? Send us your order number and we'll chase it.
Will a kit fit my bike?
Three measurements decide it.
- Rear dropout width: 1,500 to 3,000 W kits suit 135 or 150 mm. 5,000 W and 10,000 W need 150 or 170 mm.
- Wheel size: 26, 27.5 or 29 inch, matched to your bike.
- Room in the front triangle for your battery.
Error code or no power
Check the simple stuff first.
- Battery charged, switched on, and the plug pushed fully home?
- Brake levers fully released? The e-brakes cut power when pulled.
- Hall sensor and phase plugs at the motor matched colour to colour?
- Still stuck? Send the error number on the display and a photo of the controller wiring.
Which battery do I need?
Match the voltage to your kit first, then pick capacity for range.
- 1,500 W and 2,000 W kits: 48 V or 52 V.
- 3,000 W and 5,000 W kits: 72 V.
- 10,000 W kit: 72 V 40 Ah with the 100 A BMS.

Common questions
How long does shipping take?
Kits and batteries ship within 7 days. Standard delivery takes about 6 weeks and express 2–3 weeks. Tracking is emailed when your order ships. Kits and batteries often ship separately.
What warranty do I get?
Kits and batteries are covered for 1 year against manufacturing defects. Contact us within 48 hours of discovering a fault with your order number, a description and clear photos or video. Warranty depends on correct installation.
Can I change or cancel my order?
Yes, if you contact us within 7 days of ordering, before it ships. We can swap to the right size or cancel it. Once an order has shipped we can't take change-of-mind or wrong-size returns. Faulty products are covered by warranty.
What battery chemistry do you use?
Lithium-ion NCM cells from grade-A brands like LG and Samsung, depending on the pack. Every battery has a BMS protecting against short circuits, overcharging, over-discharging and over-current.
Are the kits road legal?
No. In most countries, anything this powerful isn't legal on public roads, footpaths or bike paths. Spark kits are for private land, off-road and competition use.
Do you do fat bike or special dropout sizes?
Fat and snow tyres, unusual dropout widths and special models need a quote. Use the form below with a photo of your frame.
