The smart move is not waiting until yours strands you. This is the genuine Riding Times replacement pack — the same factory battery that shipped with your bike, matched to its exact connector, voltage profile and mounting slot, with full BMS protection and a removable, lockable design. One product, eight fitment variants, covering the entire Riding Times lineup Zeus carries: Z8 — 48V 15.6Ah (~749 Wh) — fits the Z8 electric bike Z8S — 48V 20.4Ah (~979 Wh) — the higher-capacity pack for the Z8S GT54 — 48V 27Ah (~1,296 Wh) — fits the GT54 mini-motorbike GT54 Pro — 60V 25Ah (~1,500 Wh) — fits the GT54 Pro GT73 — 48V 18.2Ah (~874 Wh per pack) — fits the GT73 electric motorbike (carries two packs) GT73 Pro — 60V 18Ah (~1,080 Wh per pack) — fits the GT73 Pro (carries two packs) G63 — 48V 20.8Ah (~998 Wh) and 48V 30Ah (~1,440 Wh) — for the G63 all-terrain series Select your variant on the right, matching the model name and capacity printed on your bike or your original pack. If you are not sure which battery fits, call 1-866-938-7580 with your serial number and we will confirm before you pay. 🇨🇦 Ships from Canada · Free Canada-wide shipping · Genuine Riding Times OEM · 1-866-938-7580 — real humans answer Why Riders Buy a Spare Riding Times Battery Before They Need One Most people think of a replacement battery as a grudge purchase — something you buy two or three years from now when your original pack starts losing range. That is one reason to own one. It is not the most important. Range, doubled, on the single-battery bikes — A Z8, Z8S, GT54 or G63 carries one pack. A second battery in a pannier or backpack lets you swap mid-route and roughly double your usable range. For weekend rides, longer commutes, or any day where charging at the destination is not realistic, the spare is the difference between confidence and constantly watching the battery gauge. How to maximise eBike range → Winter performance — rotate the warm pack — Lithium loses 20 to 40% of its capacity in sub-zero temperatures. The fix is simple: keep one pack indoors warming while you ride on the other, then swap when you get home. A battery that starts at 20°C delivers meaningfully more range than a pack that started at −10°C, even at identical state-of-charge. Canadian winter is exactly the use case where a second pack beats one bigger pack. Winter eBike strategy → Dual-battery bikes keep rolling with a third pack on hand — The GT73 and GT73 Pro already carry two packs. A spare lets you keep riding while one pack charges, replace a single tired pack without buying two, or keep one warm indoors over winter. You order one pack per pack you are replacing. End-of-life replacement — planned, not panicked — Lithium-ion packs lose meaningful capacity after a few hundred full cycles — typically two to five years for most owners depending on use. Buying the replacement before the old pack fails means no missed commutes, no scrambling, no waiting on backorders. The old pack stays as your spare; the new pack becomes your daily driver. Genuine OEM keeps you compliant and keeps your warranty — Riding Times bikes are wired and tuned for specific cell configuration, BMS communication and connector pinout. An off-brand pack that physically fits the frame can still send the wrong voltage profile to the controller, fry the display, or fail the BMS handshake — and installing one typically voids your bike warranty. The OEM pack is the only one designed for that interface. Compatibility Map — Which Battery Fits Your Bike Select the variant that matches the model name on your bike and the capacity printed on your original pack. The 48V and 60V packs are not interchangeable, and capacity (Ah) varies within the lineup. Your Riding Times Bike Order This Variant Voltage Capacity Nominal Energy Z8 Z8 48V 15.6Ah ~749 Wh Z8S Z8S 48V 20.4Ah ~979 Wh G63 (20Ah version) G63 — 20Ah 48V 20.8Ah ~998 Wh G63 (30Ah version) G63 — 30Ah 48V 30Ah ~1,440 Wh GT54 GT54 48V 27Ah ~1,296 Wh GT54 Pro GT54 Pro 60V 25Ah ~1,500 Wh GT73 (two packs) GT73 48V 18.2Ah / pack ~874 Wh / pack GT73 Pro (two packs) GT73 Pro 60V 18Ah / pack ~1,080 Wh / pack Nominal energy is calculated as voltage × capacity and rounded; usable energy is slightly lower. The G63 is not currently stocked as a complete bike at Zeus — we supply its replacement packs for existing owners. Not sure which variant you need? Call 1-866-938-7580 with the model name on your bike or the label on your old pack. We confirm fitment before processing the order. Key Features Genuine Riding Times OEM pack — exact fit, no adapters — The pack drops into your bike’s existing battery slot. The connector pinout matches the controller, the mounting matches the frame, and the lock barrel aligns with the keyed cylinder. This is the same battery that came with your bike from the factory — not a “compatible” approximation. Removable design — charge and store indoors — Every variant comes out of the bike so you can bring it inside to charge, keep it warm through winter, or store it safely off-season. Removable batteries are also the single biggest theft deterrent at a bike rack — take the pack with you and the bike is far less attractive to steal. Battery Management System (BMS) protection — Active circuit protection against overcharge, over-discharge, overcurrent, short circuit and cell imbalance. The BMS regulates current during charging, balances cells across the pack to extend life, and shuts the pack down if any single cell leaves its safe voltage window. 48V and 60V options across the lineup — The Z8, Z8S, GT54, GT73 and G63 run 48V systems; the GT54 Pro and GT73 Pro step up to 60V for higher speed and power. Ordering the correct voltage is the single most important part of getting the right pack — the compatibility map above is your reference. UL 2849 compliance on the GT-series packs — Riding Times confirms UL 2849 compliance on the GT54, GT54 Pro, GT73 and GT73 Pro packs. UL 2849 is the system-level electrical safety standard for eBikes — the certification most Canadian condo boards, building insurers and municipal bylaws look for when permitting lithium batteries indoors. See the honest take below for what is, and is not, published on the Z8 and G63 packs. Voltage-matched OEM charging — Each variant pairs with its matching charger: the GT54 uses a 54.6V charger, the GT54 Pro a 67V charger, and the GT73 Pro a 67.2V charger. Slow, voltage-matched charging is the single biggest factor in long battery life — which is exactly why you should never substitute a higher-voltage or no-name “fast charger” from a third party. Supported by an authorised Canadian dealer — Replacement packs go through Zeus with Canadian inventory, Canadian shipping and Canadian phone support. No cross-border returns. No shipping a battery back to the US for warranty. No multi-week ocean freight from offshore stock.

What You Should Know Before Buying (Honest Take) Match the variant exactly — voltage first. A 60V pack will not run a 48V bike and a 48V pack will not run a 60V bike. Within the 48V group, capacity and physical mounting still differ between models. Buying the wrong variant means a return. Read the compatibility map above — or call 1-866-938-7580 if you are unsure. UL certification is published for the GT packs, not the Z8 or G63 packs. Riding Times confirms UL 2849 compliance on the GT54, GT54 Pro, GT73 and GT73 Pro. For the Z8, Z8S and G63 packs, we did not find a published UL standard in the manufacturer specs we reviewed. We would rather tell you that plainly than imply a certification we cannot point to. If indoor-charging compliance matters for your building or insurer, call us and we will confirm the current certification on your exact variant before you order. A bigger pack will not fit a bike designed for a smaller one. If you own a Z8 (15.6Ah), the Z8S (20.4Ah) pack is not a drop-in “upgrade” — order the pack your bike was built for. There is no cross-variant upgrade path that bypasses the bike’s controller and mounting. Cold-weather charging damages cells. Never charge a pack that has just come in from sub-zero temperatures. Let it warm to room temperature (one to two hours indoors) before plugging in. Charging below 0°C causes lithium plating on the anode — permanent capacity loss the BMS cannot recover. This is the most common cause of premature battery failure in Canadian winter use. Do not use third-party or wrong-voltage chargers. The OEM charger is voltage-matched and current-limited for your specific pack. A 67V charger on a 48V pack, or a high-amperage no-name “fast charger,” can push the pack past safe charge rate, accelerate ageing, and in the worst case trigger a thermal event. The replacement battery ships without a charger because most owners already have the right one. Store a spare correctly or it ages anyway. A “just in case” pack left at full charge in a hot or freezing garage for years is the worst storage condition there is. Store a spare at 40–60% charge in a cool, dry, climate-stable place, top it up to 50% every three months, and rotate it into use at least once a year. Stored well, a backup pack stays healthy for years; stored badly, it can lose meaningful capacity in 18 months. “Compatible” aftermarket packs are a false economy. A pack that slots into the frame can still fail the BMS handshake, send the wrong voltage profile, or skip safety testing entirely. Grey-market and marketplace sellers advertising “fits Riding Times” are not authorised by the manufacturer and will void your bike warranty the moment they are installed. The genuine Riding Times replacement battery is not the cheapest pack you can find online. It is the one that matches your bike’s controller exactly, keeps your warranty intact, and ships from a Canadian dealer with Canadian support behind it. If those things matter to you — and on a part this safety-critical, they should — this is the right pack. Full Specifications by Variant Scroll the table sideways on mobile to see all columns.

Owners whose original pack is losing range — If your bike no longer goes as far as it did when new, the battery is the most likely cause. A fresh OEM pack restores the range your bike was designed for — no new bike required. Long-distance riders who want range insurance — On a single-battery Z8, GT54 or G63, a second pack in a pannier turns a one-charge bike into a two-charge bike. Throw the spare in a bag and ride past the point where you would normally turn back. Long-range eBike guide → Year-round Canadian commuters — A second pack stored at room temperature, ready to swap, is the most effective winter range strategy you can buy — more effective than a single larger pack, because the cold is the problem, not the capacity. Canadian winter eBike strategy → GT73 and GT73 Pro owners — A spare third pack means you can keep riding while one charges, replace a single tired pack without buying a matched pair, or rotate a warm pack onto the bike in winter. Riders approaching the two-to-three-year mark — Your original pack is probably still working, but at 80–90% of its original capacity. Buying the replacement now — while inventory is healthy and shipping is quick — beats discovering a backorder the week your old pack quits. Rotate the new pack into daily use and keep the older one as a spare. Who probably doesn’t need one right now: Recent buyers with a healthy original pack and a short daily route — If your bike covers your commute with charge to spare and the battery is under a year old, a second pack is a “nice to have” rather than a need. Revisit at the two-to-three-year mark. Three-season riders in mild conditions — If you only ride May through September on short trips, the strongest arguments for a spare (winter and long distance) may not apply to you yet. Frequently Asked Questions Which Riding Times bike does each battery variant fit? Match the variant to the model name printed on your bike. The Z8 uses a 48V 15.6Ah pack and the Z8S a 48V 20.4Ah pack. The GT54 uses a 48V 27Ah pack; the GT54 Pro a 60V 25Ah pack. The GT73 uses a 48V 18.2Ah pack and the GT73 Pro a 60V 18Ah pack — both bikes carry two packs, so order one per pack you are replacing. The G63 comes in 48V 20.8Ah and 48V 30Ah versions — order the capacity printed on your original pack. Unsure? Call 1-866-938-7580 and we will confirm fitment from your serial number. Is this a genuine Riding Times battery or aftermarket? This is a genuine Riding Times factory pack — matched to the exact connector, voltage profile and mounting interface on your bike. Aftermarket packs from third parties may physically fit but typically void your warranty, can fail safety certification, and can damage your controller or display. Always order the OEM battery from an authorised Canadian dealer. Are these batteries UL certified? UL 2849 compliance is confirmed by Riding Times for the GT54, GT54 Pro, GT73 and GT73 Pro packs. For the Z8, Z8S and G63 packs, Riding Times does not publish a specific UL standard in the specifications we reviewed. If certification is a deciding factor for your building, insurer or condo board, call 1-866-938-7580 and we will confirm the current certification on your exact variant before you order. Can I use my charger from one model on a different variant? No. The 48V packs (Z8, Z8S, GT54, GT73, G63) and the 60V packs (GT54 Pro, GT73 Pro) use different chargers — a 67V charger will not correctly charge a 48V pack, and vice versa. Always use the OEM charger that matches your pack’s voltage. Using the wrong charger can damage the pack and is a safety hazard. Can I charge this battery indoors? Yes — every pack is removable so you can bring it inside to charge and keep warm in winter. Charge on a hard, non-flammable surface away from exits, never under a bed or behind furniture, and never leave a damaged or swollen pack on the charger. Let a cold pack warm to room temperature for one to two hours before plugging in. Does it come with a charger? No — the replacement ships as the pack itself, because your original bike came with the matching charger and most owners already have one. If you want a spare charger for work or a second residence, note it in the order comments and we will quote the correct-voltage charger for your variant. How long does the warranty last? Every pack is backed by Zeus’s complimentary 1-month limited warranty plus the standard Riding Times manufacturer warranty, with paid extended support plans available at checkout. See the Zeus warranty policy for current terms and how to file a claim. How can I finance a replacement battery? The same financing options that apply to Zeus bike purchases apply to parts and accessories at checkout — Klarna, Shop Pay Instalments and other options let you spread the cost.
