    There will certainly be more parts for Chinese inventions than for some unpopular Bosch or other expensive companies. Don`t take a bike with a motor in the bottom bracket, it`s the worst thing you can buy. HIMO will sell a whole lot of pieces. When something is sold in large quantities, there are plenty of parts. I would buy HIMO C26 MAX if it costs PLN 6,000, because when the season starts and inflation helps, you won`t find it for PLN 8,000.

    Ali`s price today is PLN 6,297.22. Shipping included in the price from Europe, i.e. no additional taxes. New original battery PLN 2,509.55. Soon they will start selling replacements and BMSs when they break down, but more of them have to be sold. Drivers and displays are already on sale.
    HIMO is signed by XIAOMI, so I suspect that the battery was made by Ninebot or some company on their behalf and they cannot afford a crap product.

Topic summary

✨ The discussion revolves around selecting an electric bike within a budget of PLN 8,000, focusing on models suitable for both road and forest use. The user expresses a preference for bikes with power assistance, particularly those with a Bosch engine, and seeks advice on essential features and components. Key considerations include motor power (max 250W), battery capacity (minimum 10Ah for 48V), and the importance of having readily available parts. Recommendations include the HIMO C26 MAX, which is noted for its affordability and availability of parts, as well as the potential for DIY battery upgrades. The conversation highlights the challenges of finding quality electric bikes within the specified budget and the rising costs of components.

FAQ

TL;DR: Used, speed‑unlocked e‑bikes start around PLN 20,000; "the minimum capacity is 10Ah (48V) or 15Ah (36V)." This FAQ helps first‑time buyers pick a mixed road/forest e‑bike on PLN 6k–8k, covering legal limits, motors, batteries, prices, and parts. [Elektroda, Anonymous, post #19944970]

Quick Facts

What e‑bike would you pick for PLN 6k–8k for road + forest?

For this budget, posters pointed to HIMO, for example the C26 MAX. It was listed around PLN 6,297 with EU shipping included. A new original battery cost about PLN 2,509. Drivers and displays are already available as spare parts. One poster added, "HIMO is signed by XIAOMI." That suggests broader supply support. Check current stock and delivery terms before buying. [Elektroda, jarroQ, post #19947374]

Do I have to obey the 250W/25 km/h rule on public roads?

Yes. If you ride bike paths or public roads, follow three rules. The poster wrote, "shifter is prohibited." The motor must be max 250W. The assist must be limited to 25 km/h by a limiter. That keeps your e‑bike within road norms. [Elektroda, Anonymous, post #19944582]

Is removing the speed limiter worth it on a budget?

One poster cautioned that speed‑unlocking reshapes your budget. He wrote, "the price list for such a bike starts from PLN 20,000, and it's used." Higher speed pushes you toward stronger batteries. They suggested moving to 48V when 36V feels weak. Expect costs to climb. [Elektroda, Anonymous, post #19944970]

36V or 48V—what should I choose at this budget?

Choose 48V if 36V feels weak. The poster advised, "look towards 48V." For forest use they suggested minimums: 10Ah at 48V or 15Ah at 36V. Use those baselines to size your pack. [Elektroda, Anonymous, post #19944970]

Is 48V 10Ah enough for short 10–30 km rides?

For forest assistance, one poster called 10Ah at 48V a minimum. For short "around the chimney" rides, that capacity can suffice. If climbs are frequent, consider more capacity or 36V with 15Ah as a baseline. Match the pack to terrain. [Elektroda, Anonymous, post #19944970]

Front hub vs rear hub vs mid‑drive—which suits mixed road/forest?

One poster summarized trade‑offs. "For the forest, it is power assisted on the front wheel." Rear‑hub assistance brings fewer maintenance issues. The greatest comfort is assistance in the bottom bracket. Choose based on upkeep, traction, and ride feel. [Elektroda, Anonymous, post #19944582]

Are mid‑drive systems a bad idea under PLN 8k?

A poster warned against mid‑drives at this tier. "Don't take a bike with a motor in the bottom bracket, it's the worst thing you can buy." They favored mass‑sold options like HIMO. "When something is sold in large quantities, there are plenty of parts." [Elektroda, jarroQ, post #19946476]

How fast can an unlocked e‑bike go?

One rider reported 72 km/h on a 2020 Trek Powerfly with the limiter removed. They were in Norway on a high‑end model. Speed depends on setup, terrain, and rider. [Elektroda, Anonymous, post #19944984]

Will I pay extra VAT when ordering from EU warehouses?

A poster noted AliExpress listed PLN 6,297.22 with shipping from Europe. They said that means no additional taxes. Confirm the warehouse location and VAT handling at checkout before purchasing. [Elektroda, jarroQ, post #19947374]

What risks come with direct manufacturer shipments and tiny batteries?

A poster warned stock was uncertain and shipments came from the manufacturer. VAT and transport costs were unclear. They added, be careful not to buy a 4Ah "banana" pack; it "will explode at the first hill." Treat very small packs as unsuitable for hills. [Elektroda, Anonymous, post #19946598]

Are there service or DRM locks to watch for?

Yes. "A used battery is practically a battery with DRM," one poster wrote. Replacement may require shipping the entire bike to service. They claimed service can charge triple what the bike cost. Encrypted protocols can block DIY diagnostics. Plan for higher maintenance costs. [Elektroda, Anonymous, post #19946598]

Can I convert my current bike instead of buying new?

Yes. A forum user linked kits that replace a wheel with a hub motor. See ekonapedy.com for wheel kits and related components. This can stretch a tight budget if your donor bike fits the task. Check compatibility and local road rules first. [Elektroda, Pi111, post #19949141]

Should I buy now or wait for the season?

One poster advised buying before peak season. HIMO around PLN 6,000 was cited, but rising fast. They wrote you "won't find it for PLN 8,000" once season and inflation hit. Stock tightens quickly when demand spikes. [Elektroda, jarroQ, post #19946476]

How do I choose fast? Give me 3 steps.

  1. Decide if you will ride on public roads or paths. Follow the three rules. 2. Pick motor placement: rear‑hub for fewer maintenance issues, mid‑drive for comfort, front‑hub for forest use. 3. Ensure a 25 km/h assist limiter if you will ride on roads. [Elektroda, Anonymous, post #19944582]
